I think there are some potential issues with doubling separators and final separators on dirs. On Unix file systems /part1//part2 and /path/to/dir/ are valid. However, file systems on Unix may not be Unix file systems: examples are earlier MacOS systems on MacOS X and mounted Windows and Novell systems on Linux. I would not want to assume that all of these combinations worked. > Gabor also suggested an option to use shell globbing instead of > regular expressions to select the files in the list, e.g. > > list.files(dir="/", pattern="a*.dat", glob=T) > > This would be easy to do in Windows, but from the little I know about > Unix programming, would not be so easy there, so I haven't done > anything about it. It would be shell-dependent and OS-dependent as well as a retrograde step, as those who wanted to use regular expressions no longer would be able to. -- Brian D.
