List of GERDA Data
Description
This function lists the available GERDA data sets. The purpose of this function is to quickly provide a list of available data sets and their descriptions.
Usage
gerda_data_list(print_table = TRUE)
Arguments
print_table |
A logical value indicating whether to print the table in the console (TRUE) or return the data as a tibble (FALSE). Default is TRUE. |
Value
A tibble containing the available GERDA data with descriptions. When print_table = TRUE, the function prints a formatted table to the console and invisibly returns the data tibble. When print_table = FALSE, the function directly returns the data tibble.
Examples
gerda_data_list()
Load GERDA Data
Description
This function loads GERDA data from a web source.
Usage
load_gerda_web(file_name, verbose = FALSE, file_format = "rds")
Arguments
file_name |
A character string specifying the name of the file to load. For a list of available data, see |
verbose |
A logical value indicating whether to print additional messages to the console. Default is FALSE. |
file_format |
A character string specifying the format of the file. Must be either "csv" or "rds". Default is "rds". |
Value
A tibble containing the loaded data, or NULL if the data could not be loaded.
Examples
# Load harmonized municipal elections data
data_municipal_harm <- load_gerda_web("municipal_harm", verbose = TRUE, file_format = "rds")
# Load federal election data harmonized to 2025 boundaries (includes 2025 election)
data_federal_2025 <- load_gerda_web("federal_muni_harm_25", verbose = TRUE, file_format = "rds")
GERDA
Description
This function creates a crosswalk between parties and their corresponding names using the ParlGov view_party table. In cases where the party name is not found in the view_party table, the function returns NA. Note that this function should be run on GERDA party names, and will likely not work on other party naming schemes.
Usage
party_crosswalk(party_gerda, destination)
Arguments
party_gerda |
A character vector containing the GERDA party names to be converted. |
destination |
The name of the column in the view_party table to map to. |
Value
A vector with the mapped party names.
Examples
party_crosswalk(c("cdu", "spd", "linke_pds", NA), "left_right")
