how to delete a file with R? [duplicate]
How about:
#Define the file name that will be deleted
fn <- "foo.txt"
#Check its existence
if (file.exists(fn)) {
#Delete file if it exists
file.remove(fn)
}
As far as I know, this is a permanent, non-recoverable (i.e. not "move to recycle bin") on all platforms ...
One of the reasons R cannot be safely exposed to outside users is that it offers complete access to system facilities. In addition to the list.files, list.dirs and the file.remove functions, the system function allows access to pretty much any exploit imaginable.
