Well, I was trying to download a .gz file and download.file() didn't detect
that. Reason for that is obviously that the link doesn't contain .gz but
%2Egz , using the ASCII code for the dot instead of the dot itself. That's
general practice in a lot of links.
Hence I propose to change the line in download.file() that does this check
to:
if (missing(mode) && length(grep("\\.(gz|bz2|xz|tgz|zip|rda|RData)$",
URLdecode(url))))
using URLdecode() ensures that .gz, .RData etc will be detected correctly
in an encoded URL.
Cheers
