I'm curious about something: does "file extension" have a standard definition? Most (all? I haven't tried them all) of the solutions presented in this thread would return an empty string for the "plain base" if given the filename ".bashrc".
right; there's a straightforward fix to my solution that accounts for
cases such as '.bashrc':
names = c("foo.bar", ".zee")
sub("(.+)[.][^.]+$", "\\1", names)
you could also use a lookbehind if possible (not in r, afaik).
or:
sub(".*[.]", ".", names)
[1] ".bar" ".zee"
