The file_path_sans_ext() function in the 'tools' package does not handle
alphanumeric file extensions correctly:
require(tools)
file_path_sans_ext("song.txt") # song, correct
file_path_sans_ext("song.mp3") # song.mp3, wrong
The help page states that "only purely alphanumeric extensions are
recognized", which I had expected. To fulfill this, the function body
should be
sub("([^.]+)\\.[[:alnum:]]+$", "\\1", x)
instead of the current definition:
sub("([^.]+)\\.[[:alpha:]]+$", "\\1", x)
Thanks,
Arni
