Hi, all,
I'm looking a utility for removing a directory from within R. Currently,
I'm using:
foo <- function(...) {
mydir <- tempdir()
dir.create(mydir, showWarnings = FALSE, recursive = TRUE)
on.exit(system(sprintf("rm -rf %s", mydir)))
## do some stuff in "mydir"
invisible()
}
However, this is assumes "rm" is available. I know of ?dir.create, but
there is no opposite. And ?file.remove appears to work only on files and
not directories.
Any advice? Or is my current approach the only solution?

Please ignore. I forgot ?unlink had a recursive argument. Thanks. --sundar Sundar Dorai-Raj wrote:> Hi, all, > > I'm looking a utility for removing a directory from within R.

?unlink says that unlink() can remove directories (and has a 'recursive' argument). 'unlink' is in the "SEE ALSO" section in ?file.remove. -- Tony Plate Sundar Dorai-Raj wrote:> Hi, all, > > I'm looking a utility for removing a directory from within R.
