Description

According to https://stat.ethz.ch/R-manual/R-devel/library/utils/html/download.file.html

"On Windows, if mode is not supplied (missing()) and url ends in one of .gz, .bz2, .xz, .tgz, .zip, .rda, .rds or .RData, mode = "wb" is set such that a binary transfer is done to help unwary users.
Code written to download binary files must use mode = "wb" (or "ab"), but the problems incurred by a text transfer will only be seen on Windows."
