Consistent palette calls

Description

These functions assist in calling particular parts of a theme's palette. For example, ag_base() will return the current theme's base or background color, and ag_highlight() will return the color used in that theme to highlight one or more nodes, lines, or such.

Usage

ag_base()

ag_highlight()

ag_positive()

ag_negative()

ag_qualitative(number)

ag_sequential(number)

ag_divergent(number)

ag_font()

Arguments

number

Integer of how many category colours to return.

Value

One or more hexcodes as strings.


Description

The function uses approximate pattern matching to redistribute coarse layouts on square grid points, while preserving the topological relationships among the nodes (see Inoue et al. 2012).

Usage

depth_first_recursive_search(layout)

Layout algorithms based on configurational positions

Description

Configurational layouts locate nodes at symmetric coordinates to help illustrate particular configurations. Currently configurational layouts are available for 2-6 nodes. The "configuration" layout will choose the appropriate configurational layout automatically.

Usage

layout_configuration(.data, circular = TRUE, times = 1)

layout_tbl_graph_configuration(.data, circular = TRUE, times = 1)

layout_dyad(.data, circular = TRUE, times = 1)

layout_tbl_graph_dyad(.data, circular = TRUE, times = 1)

layout_triad(.data, circular = TRUE, times = 1)

layout_tbl_graph_triad(.data, circular = TRUE, times = 1)

layout_tetrad(.data, circular = TRUE, times = 1)

layout_tbl_graph_tetrad(.data, circular = TRUE, times = 1)

layout_pentad(.data, circular = TRUE, times = 1)

layout_tbl_graph_pentad(.data, circular = TRUE, times = 1)

layout_hexad(.data, circular = TRUE, times = 1)

layout_tbl_graph_hexad(.data, circular = TRUE, times = 1)

Arguments

.data

Some {manynet} compatible network data.

circular

Logical, required for {ggraph} compatibility, default TRUE.

times

Integer, how many times to run the algorithm. Required by for {ggraph} compatibility, but not used here, so default = 1.

Layered layout

Description

Layered layout

Usage

layout_tbl_graph_layered(.data, center = NULL, circular = FALSE, times = 4)

Arguments

.data

Some {manynet} compatible network data.

center, circular

Extra parameters required for {tidygraph} compatibility.

times

Integer of sweeps that the algorithm will pass through. By default 4.

Value

Returns a table of coordinates.

Examples

ties <- data.frame(
  from = c("A", "A", "B", "C", "D", "F", "F", "E"),
  to   = c("B", "C", "D", "E", "E", "E", "G", "G"),
  stringsAsFactors = FALSE)

coords <- layout_tbl_graph_layered(ties, times = 6)
coords

Matching layout

Description

This layout works to position nodes opposite their matching nodes. See manynet::to_matching() for more details on the matching procedure.

Usage

layout_tbl_graph_matching(.data, center = NULL, circular = FALSE, times = 1)

Arguments

.data

Some {manynet} compatible network data.

center, circular, times

Extra parameters required for {tidygraph} compatibility.

Value

Returns a table of nodes' x and y coordinates.


Layout algorithms based on bi- or other partitions

Description

These algorithms layout networks based on two or more partitions, and are recommended for use with graphr() or {ggraph}. Note that these layout algorithms use {Rgraphviz}, a package that is only available on Bioconductor. It will first need to be downloaded using BiocManager::install("Rgraphviz"). If it has not already been installed, there is a prompt the first time these functions are used though.

The "hierarchy" layout layers the first node set along the bottom, and the second node set along the top, sequenced and spaced as necessary to minimise edge overlap. The "alluvial" layout is similar to "hierarchy", but places successive layers horizontally rather than vertically. The "railway" layout is similar to "hierarchy", but nodes are aligned across the layers. The "ladder" layout is similar to "railway", but places successive layers horizontally rather than vertically. The "concentric" layout places a "hierarchy" layout around a circle, with successive layers appearing as concentric circles. The "multilevel" layout places successive layers as multiple levels. The "lineage" layout ranks nodes in Y axis according to values.

Usage

layout_concentric(
  .data,
  membership,
  radius = NULL,
  order.by = NULL,
  circular = FALSE,
  times = 1000
)

layout_tbl_graph_concentric(
  .data,
  membership,
  radius = NULL,
  order.by = NULL,
  circular = FALSE,
  times = 1000
)

layout_multilevel(.data, level, circular = FALSE)

layout_tbl_graph_multilevel(.data, level, circular = FALSE)

layout_lineage(.data, rank, circular = FALSE)

layout_tbl_graph_lineage(.data, rank, circular = FALSE)

layout_hierarchy(.data, center = NULL, circular = FALSE, times = 1000)

layout_tbl_graph_hierarchy(
  .data,
  center = NULL,
  circular = FALSE,
  times = 1000
)

layout_alluvial(.data, circular = FALSE, times = 1000)

layout_tbl_graph_alluvial(.data, circular = FALSE, times = 1000)

layout_railway(.data, circular = FALSE, times = 1000)

layout_tbl_graph_railway(.data, circular = FALSE, times = 1000)

layout_ladder(.data, circular = FALSE, times = 1000)

layout_tbl_graph_ladder(.data, circular = FALSE, times = 1000)

Arguments

.data

Some {manynet} compatible network data.

membership

A node attribute or a vector to draw concentric circles for "concentric" layout.

radius

A vector of radii at which the concentric circles should be located for "concentric" layout. By default this is equal placement around an empty centre, unless one (the core) is a single node, in which case this node occupies the centre of the graph.

order.by

An attribute label indicating the (decreasing) order for the nodes around the circles for "concentric" layout. By default ordering is given by a bipartite placement that reduces the number of edge crossings.

circular

Should the layout be transformed into a radial representation. Only possible for some layouts. Defaults to FALSE.

times

Maximum number of iterations, where appropriate

level

A node attribute or a vector to hierarchically order levels for "multilevel" layout.

rank

A numerical node attribute to place nodes in Y axis according to values for "lineage" layout.

center

Further split "hierarchical" layouts by declaring the "center" argument as the "events", "actors", or by declaring a node name in hierarchy layout. Defaults to NULL.

plot(ergm_res$sample)

Plotting goodness-of-fit results

Description

These plot methods plot goodness of fit objects created using RSiena::sienaGOF(), MoNAn::monanGOF(), or the 'ergm' package's gof() function. Internally, the GOF object is translated into a common class (ag_gof), which has its own plot method to ensure a consistent look and feel. It is not expected that users will create ag_gof class objects themselves.

The plot shows a violin plot of the distribution of statistics from the simulations, with a boxplot inside the violin to show the interquartile range, and dashed lines connecting the 5th and 95th percentiles. The boxplot also shows outliers as crosses. The observed statistics are shown as points and connected by a line. The observed statistics are also labelled with their value. If a p-value is available (as in the case of RSiena::sienaGOF()), it is shown beneath the x-axis.

Usage

## S3 method for class 'ag_gof'
plot(x, ...)

## S3 method for class 'gof.stats.monan'
plot(x, cumulative = FALSE, ...)

## S3 method for class 'sienaGOF'
plot(x, cumulative = FALSE, ...)

## S3 method for class 'gof.ergm'
plot(x, cumulative = FALSE, statistic = c("deg", "espart", "dist"), ...)

Arguments

x

An object of class "sienaGOF", "gof.stats.monan", or "gof.ergm".

...

Other parameters to be passed to the plotting function, for example main = "Title" for a different title than the default.

cumulative

Logical, indicating whether the statistics should be plotted cumulatively (default FALSE). This is typically treated in sienaGOF() for {RSiena}, but treated within the plotting function for {MoNAn} and 'ergm'.

statistic

Character, indicating which statistic to plot. Since 'ergm' package GOFs include goodness of fit on multiple statistics, the user must specify which statistic to plot. Options are "deg" (degree distribution), "espart" (edgewise shared partners), and "dist" (geodesic distance). The default is "deg".

Details

Since these plots methods are in {autograph}, the plots are automatically themed according to the current theme set using stocnet_theme(). The function uses the highlight colour defined in the current theme to highlight the observed statistics. The function also uses the base colour defined in the current theme to draw the violin and box plots.

It is however completely customisable. While a title is automatically generated so that the graph is informative, this can be customised by specifying the main argument in the plotting function, or added after the fact using {ggplot2} functions such as ggtitle() or labs().

The user can choose whether to plot the statistics cumulatively or not. This is typically handled within RSiena::sienaGOF(), but for MoNAn::monanGOF() and the 'ergm' package's gof() function the cumulative option is handled here. The default is to plot the non-cumulative statistics. This is because the non-cumulative statistics are often more interpretable, and the cumulative statistics can be obtained by setting cumulative = TRUE.

The function also checks whether any of the statistics have zero variance across the simulations, and if so, these statistics are not plotted, with a message to the user indicating which statistics were omitted.

Note that these methods overwrite any plot methods for these classes that may be provided by the original packages. You may receive such a warning in the console when loading the package. Please load {autograph} after these other packages to ensure the plotting methods included in this package are used, or specify the package when calling the plotting method directly, e.g., autograph:::plot.sienaGOF(res_siena_gof).

Value

A violin plot showing the distribution of statistics from the simulations and a line joining points showing the observed statistics.

Easily graph networks with sensible defaults

Description

This function provides users with an easy way to graph (m)any network data for exploration, investigation, inspiration, and communication.

It builds upon {ggplot2} and {ggraph} to offer pretty and extensible graphing solutions. However, compared to those solutions, graphr() contains various algorithms to provide better looking graphs by default. This means that just passing the function some network data will often be sufficient to return a reasonable-looking graph.

The function also makes it easy to modify many of the most commonly adapted aspects of a graph, including node and edge size, colour, and shape, as arguments rather than additional functions that you need to remember. These can be defined outright, e.g. node_size = 8, or in reference to an attribute of the network, e.g. node_size = "wealth".

Lastly, graphr() uses {ggplot2}-related theme information, so it is easy to make colour palette and fonts institution-specific and consistent. See e.g. theme_iheid() for more.

To learn more about what can be done visually, try run_tute("Visualisation").

Usage

graphr(
  .data,
  layout,
  labels = TRUE,
  node_color,
  node_shape,
  node_size,
  node_group,
  edge_color,
  edge_size,
  snap = FALSE,
  ...,
  node_colour,
  edge_colour
)

Arguments

.data

A manynet-consistent object.

layout

An igraph, ggraph, or manynet layout algorithm. If not declared, defaults to "triad" for networks with 3 nodes, "quad" for networks with 4 nodes, "stress" for all other one mode networks, or "hierarchy" for two mode networks. For "hierarchy" layout, one can further split graph by declaring the "center" argument as the "events", "actors", or by declaring a node name. For "concentric" layout algorithm please declare the "membership" as an extra argument. The "membership" argument expects either a quoted node attribute present in data or vector with the same length as nodes to draw concentric circles. For "multilevel" layout algorithm please declare the "level" as extra argument. The "level" argument expects either a quoted node attribute present in data or vector with the same length as nodes to hierarchically order categories. If "level" is missing, function will look for 'lvl' node attribute in data. The "lineage" layout ranks nodes in Y axis according to values. For "lineage" layout algorithm please declare the "rank" as extra argument. The "rank" argument expects either a quoted node attribute present in data or vector with the same length as nodes.

labels

Logical, whether to print node names as labels if present.

node_color, node_colour

Node variable to be used for coloring the nodes. It is easiest if this is added as a node attribute to the graph before plotting. Nodes can also be colored by declaring a color instead.

node_shape

Node variable to be used for shaping the nodes. It is easiest if this is added as a node attribute to the graph before plotting. Nodes can also be shaped by declaring a shape instead.

node_size

Node variable to be used for sizing the nodes. This can be any continuous variable on the nodes of the network. Since this function expects this to be an existing variable, it is recommended to calculate all node-related statistics prior to using this function. Nodes can also be sized by declaring a numeric size or vector instead.

node_group

Node variable to be used for grouping the nodes. It is easiest if this is added as a hull over groups before plotting. Group variables should have a minimum of 3 nodes, if less, number groups will be reduced by merging categories with lower counts into one called "other".

edge_color, edge_colour

Tie variable to be used for coloring the nodes. It is easiest if this is added as an edge or tie attribute to the graph before plotting. Edges can also be colored by declaring a color instead.

edge_size

Tie variable to be used for sizing the edges. This can be any continuous variable on the nodes of the network. Since this function expects this to be an existing variable, it is recommended to calculate all edge-related statistics prior to using this function. Edges can also be sized by declaring a numeric size or vector instead.

snap

Logical scalar, whether the layout should be snapped to a grid.

...

Extra arguments to pass on to the layout algorithm, if necessary.

Value

A ggplot2::ggplot() object. The last plot can be saved to the file system using ggplot2::ggsave().

  mutate_ties(ecolor = rep(c("friends", "acquaintances"), times = 5)) %>%
  graphr(node_color = "color", node_size = "size",
         edge_size = 1.5, edge_color = "ecolor")

Easily graph a set of networks with sensible defaults

Description

This function provides users with an easy way to graph lists of network data for comparison.

It builds upon this package's graphr() function, and inherits all the same features and arguments. See graphr() for more. However, it uses the {patchwork} package to plot the graphs side by side and, if necessary, in successive rows. This is useful for lists of networks that represent, for example, ego or component subgraphs of a network, or a list of a network's different types of tie or across time. By default just the first and last network will be plotted, but this can be overridden by the "waves" parameter.

Where the graphs are of the same network (same nodes), the graphs may share a layout to facilitate comparison. By default, successive graphs will use the layout calculated for the "first" network, but other options include the "last" layout, or a mix, "both", of them.

Usage

graphs(netlist, waves, based_on = c("first", "last", "both"), ...)

Arguments

netlist

A list of manynet-compatible networks.

waves

Numeric, the number of plots to be displayed side-by-side. If missing, the number of plots will be reduced to the first and last when there are more than four plots. This argument can also be passed a vector selecting the waves to plot.

based_on

Whether the layout of the joint plots should be based on the "first" or the "last" network, or "both".

...

Additional arguments passed to graphr().

Value

Multiple ggplot2::ggplot() objects displayed side-by-side.

Easily animate dynamic networks with sensible defaults

Description

This function provides users with an easy way to graph dynamic network data for exploration and presentation.

It builds upon this package's graphr() function, and inherits all the same features and arguments. See graphr() for more. However, it uses the {gganimate} package to animate the changes between successive iterations of a network. This is useful for networks in which the ties and/or the node or tie attributes are changing.

A progress bar is shown if it takes some time to encoding all the .png files into a .gif.

Usage

grapht(
  tlist,
  keep_isolates = TRUE,
  layout,
  labels = TRUE,
  node_color,
  node_shape,
  node_size,
  edge_color,
  edge_size,
  ...,
  node_colour,
  edge_colour
)

Arguments

tlist

The same migraph-compatible network listed according to a time attribute, waves, or slices.

keep_isolates

Logical, whether to keep isolate nodes in the graph. TRUE by default. If FALSE, removes nodes from each frame they are isolated in.

layout

An igraph, ggraph, or manynet layout algorithm. If not declared, defaults to "triad" for networks with 3 nodes, "quad" for networks with 4 nodes, "stress" for all other one mode networks, or "hierarchy" for two mode networks. For "hierarchy" layout, one can further split graph by declaring the "center" argument as the "events", "actors", or by declaring a node name. For "concentric" layout algorithm please declare the "membership" as an extra argument. The "membership" argument expects either a quoted node attribute present in data or vector with the same length as nodes to draw concentric circles. For "multilevel" layout algorithm please declare the "level" as extra argument. The "level" argument expects either a quoted node attribute present in data or vector with the same length as nodes to hierarchically order categories. If "level" is missing, function will look for 'lvl' node attribute in data. The "lineage" layout ranks nodes in Y axis according to values. For "lineage" layout algorithm please declare the "rank" as extra argument. The "rank" argument expects either a quoted node attribute present in data or vector with the same length as nodes.

labels

Logical, whether to print node names as labels if present.

node_color, node_colour

Node variable to be used for coloring the nodes. It is easiest if this is added as a node attribute to the graph before plotting. Nodes can also be colored by declaring a color instead.

node_shape

Node variable to be used for shaping the nodes. It is easiest if this is added as a node attribute to the graph before plotting. Nodes can also be shaped by declaring a shape instead.

node_size

Node variable to be used for sizing the nodes. This can be any continuous variable on the nodes of the network. Since this function expects this to be an existing variable, it is recommended to calculate all node-related statistics prior to using this function. Nodes can also be sized by declaring a numeric size or vector instead.

edge_color, edge_colour

Tie variable to be used for coloring the nodes. It is easiest if this is added as an edge or tie attribute to the graph before plotting. Edges can also be colored by declaring a color instead.

edge_size

Tie variable to be used for sizing the edges. This can be any continuous variable on the nodes of the network. Since this function expects this to be an existing variable, it is recommended to calculate all edge-related statistics prior to using this function. Edges can also be sized by declaring a numeric size or vector instead.

...

Extra arguments to pass on to the layout algorithm, if necessary.

Value

Shows a .gif image. Assigning the result of the function saves the gif to a temporary folder and the object holds the path to this file.

Plotting effects interpretation

Description

These functions support the interpretation of network and behavior effects found in stochastic actor-oriented models. They are S3 plotting methods for objects of class "selectionTable" or "influenceTable", created using RSiena::selectionTable() or RSiena::influenceTable(), respectively. They plot how the evaluation function for selection or influence changes based on ego's value and alter's value of some covariate. This helps to interpret the effect of that covariate on the network dynamics or behavior dynamics, respectively.

Usage

## S3 method for class 'selectionTable'
plot(x, quad = TRUE, separation = 0, ...)

## S3 method for class 'influenceTable'
plot(x, separation = 0, ...)

Arguments

x

An object of class "selectionTable" or "influenceTable", created using RSiena::selectionTable() or RSiena::influenceTable(), respectively.

quad

When TRUE (the default), a quadratic function (average and total alter) is plotted. Use quad = FALSE for similarity effects.

separation

This can be used to make the curves visually distinguishable if they overlap too much without it. An advisable value then is, e.g., 0.01.

...

Other arguments to be passed.

Details

These functions were originally written by Tom Snijders, and adapted for use in the {autograph} package.

Value

A plot showing how the selection/influence evaluation function changes based on ego's value and alter's value of some covariate.

Matching colors across palettes

Description

Sometimes a palette or particular colours are chosen to symbolise or represent a particular idea, such as red for "stop" or green for "go", or to convey some other interpretation. Yet institutional palettes do not necessarily include all colours, which can constrain how interpretable visualisations are under institutional branding requirements. match_color() helps to find the closest matching colours in a given palette to one or more input colours.

There is also a helper function, is_dark(), to determine whether a color is dark or light, which can be useful when deciding whether to use white or black text on top of a colored background.

Usage

match_color(colors, pal)

is_dark(colors)

Arguments

colors

One or more hexcodes to match with colors from the palette.

pal

Optionally, a vector of hexcodes representing a palette in which to find matches. By default, the current theme's qualitative palette is used.

Details

This function uses the Euclidean distance of colours in CIELAB space to those of a target palette to find the closes corresponding colours. It also ensures that each input color is matched to a unique color in the palette. If there are more input colors than unique colors in the palette, an error is returned.

By default, the current theme's qualitative palette is used, but any vector of hexcodes can be passed to the pal argument.

Value

A vector of hexcodes the length of the first argument.

Examples

match_color("#4575b4")
is_dark(c("#000","#FFF"))

Setting a consistent theme for all plots

Description

This function enables plots to be quickly, easily and consistently themed. This is achieved by setting a theme option, usually at the start of an R session, that enables the palette to be used for all autograph-consistent plotting methods. This includes thematic colours for backgrounds, highlights, sequential, divergent and categorical colour schemes. The function sets these palettes to options that are then used by the various plotting functions.

If no theme is specified (i.e. the function is called without argument), the current theme is reported. The default theme is "default". This theme uses a white background, blue and red for highlighting, and a blue-white-red divergent palette. The themes can be changed at any time by calling stocnet_theme() or its alias set_stocnet_theme() with a different theme name.

Other themes include those based on the colour schemes of various universities, including ETH Zurich, UZH, UNIBE, RUG, and Oxford. Other themes include "bw" for black and white, "crisp" for a high-contrast black and white theme, "neon" for a dark theme with neon highlights, and "rainbow" for a colourful theme. Most themes are designed to be colour-blind safe.

Usage

stocnet_theme(theme = NULL)

set_stocnet_theme(theme = NULL)

Arguments

theme

String naming a theme. By default "default". The following themes are currently available: default, bw, crisp, neon, iheid, ethz, uzh, rug, unibe, oxf, unige, cmu, rainbow. This string can be capitalised or not.

Value

This function sets the theme and palette(s) to be used across all stocnet packages. The palettes are written to options and held there.

Fonts

Some themes also set a preferred font for use in plots, if available on the system (a check is performed). In some cases, this includes a vector of options to try in sequence. If none of the preferred fonts are available, a sans-serif font is used. If you receive a warning about a missing font when setting a theme, try installing one of the preferred fonts or make sure that the font is available to R using extrafont::font_import() and extrafont::loadfont()

Examples

stocnet_theme("default")
plot(manynet::node_degree(ison_karateka))
stocnet_theme("rug")
plot(manynet::node_degree(ison_karateka))
