Bioatles data is projected in European Datum 1950 (31N). The function bioatles(), which downloads the occurrences, also transform the data set in Lat/Long Geographic Coordinates System WGS84. It is based on several functions included in the packages "rvest" (Wickham, 2016) and "xml2" (Wickham et al., 2017). Finally, it saves the data in a csv file.
Equally, GetBIF() is used to download species occurrences from GBIF. It is based on several functions included in the package "rgbif" (Chamberlain, 2017). It uses the so-called "/occurrence/download route" (see vignettes of the "rgbif" package) which is more appropriate for big data sets. GetBIF() retrieve your GBIF credentials (user, password and email) and automatically makes checks using a loop until the request of the data set made to GBIF is ready. In that moment it starts the download. Finally, it saves the data in a csv file. The data is in Lat/Long Geographic Coordinates System WGS84.
See vignette for some examples.
