Hi, assume I have an existing file 'pathname' and I want to rename it to 'pathnameN' (which does not exist). I use:
res <- file.rename(pathname, pathnameN); Is it guaranteed that: (1) if res == TRUE, the file now have name 'pathnameN' and there is no file with name 'pathname'? (2) if res == FALSE, nothing has changed? or could it theoretically also be the case that (3) there are say two identical files named 'pathname' and 'pathnameN', (4) or worse, that neither exists? I can see how (3) could happen if the file is renamed by first using file.copy() and then file.remove() while there is lack of write/delete permission for the latter. Currently, my code asserts that (3) and (4) did not happen. Is that unnecessary - does file.rename() do that for me (regardless of OS)?
