dir(all=TRUE) returns the file names "." and ".." while dir(recursive=TRUE, all=TRUE, include.dirs=TRUE) does not. I always filter out the "." and ".." entries and was wondering if anyone would mind if dir(all=TRUE) just omitted them? It might make recursive file operations like cleaning out a directory safer, as unlink(recursive=TRUE, dir(all=TRUE, "dirToClean")) might start attacking dirToClean/.., then dirToClean/../.., etc., until your disk is empty.
