Changelog

fix for get_geodata(geolevel="zh_counting_districts") and additional checks to ensure functions fail gracefully in case of availability and connection problems.

fix for get_geodata() / plot_nationalvotes()
gentle failure of the swissdd-function in case of errors in the data source / problems with the API
bug fixes for get_geodata() / plot_nationalvotes()

minor modification to the ‘plot_cantonalvotes()’-function to ensure that the function works even when there are no results yet for an upcoming vote.

major update : new functions to retrieve geodata of voting districts and plot vote results maps have been added by David Zumbach (Thanks a thousand David!)

the canton_json_to_dfr has been adapted to work with the altered data structure of the json files provided via opendata.swiss containing the cantonal vote results.

Functions renamed (breaking change): to retrieve real time or archive results data via opendata.swiss, the function get_nationalvotes must be used. get_swissvotes is turned into the function that allows to get Swissvotes-Data.
New function that allows to retrieve Swissvotes-Data added (get_swissvotes)
option to retrieve counting district level data with the get_nationalvotes()- and get_cantonalvotes()-functions added (affects Zurich and Winterthur only)
functions adapted to new tidyr API, the package now depends on tidyr >= 1.0.0.

Added parent level ids to district and municipality level results (canton / district)
New function that calculates correlations between votes added: similar_votes()
Better error handling with fallback if votedate information provided on opendata.swiss is corrupt
Improved speed of data-retrieval. Comparison:
