Re: [R] deleting a directory

?unlink says that unlink() can remove directories (and has a 'recursive' 
argument).  'unlink' is in the "SEE ALSO" section in ?file.remove.

Please ignore. I forgot ?unlink had a recursive argument.

Thanks.

[R] deleting a directory

2006-08-01 Thread Sundar Dorai-Raj 
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?
