There are growing concerns on flow data in diverse fields including trade, migration, knowledge diffusion, disease spread, and transportation. The package is an effective visual support to learn the pattern of flow which is called halfcircle diagram. The flow between two nodes placed on the center line of a circle is represented using a half circle drawn from the origin to the destination in a clockwise direction. Through changing the order of nodes, the halfcircle diagram enables users to examine the complex relationship between bidirectional flow and each potential determinants. Furthermore, the halfmeancenter function, which calculates (un) weighted mean center of half circles, makes the comparison easier.

Build better balance in causal inference models. 'halfmoon'
    helps you assess propensity score models for balance between groups
    using metrics like standardized mean differences and visualization
    techniques like mirrored histograms. 'halfmoon' supports both
    weighting and matching techniques.

Provides methods for implementing hierarchical age length keys
    to estimate fish ages from lengths using data borrowing. Users can create
    hierarchical age length keys and use them to assign ages given length.

Various functions and algorithms are provided here for solving optimal matching tasks in the context of preclinical cancer studies. Further, various helper and plotting functions are provided for unsupervised and supervised machine learning as well as longitudinal mixed-effects modeling of tumor growth response patterns.

Shiny-App that allows to annotate vectors of texts to predefined categories by hand.

Converts among many citation formats, including 'BibTeX',
    'Citeproc', 'Codemeta', 'RDF XML', 'RIS', 'Schema.org', and
    'Citation File Format'. A low level 'R6' class is provided, as well
    as stand-alone functions for each citation format for both read
    and write.
