[Rd] file.copy

[Herve Pages]

Hi,

Copying a non-existing file with file.copy creates an empty file

  > r <- file.copy("non-existing-file", ".")
  > r
  [1] TRUE

... and returns TRUE!

Now, when used in "vectorized" mode

  > r <- file.copy(c("toto1", "toto2"), c("dest1", "dest2"))
  [1] FALSE FALSE

file.copy looks much more reasonable, except that files "dest1"
and "dest2" are still created (despite the fact that "toto1" and
"toto2" don't exist).

If the 'to' argument is not a dir:

  > r <- file.copy(c("toto3", "toto4"), ".")
  > r
  [1] TRUE TRUE

!!?!?

May be those are (undocumented) features, but I bet 99.9% of the users would
expect something different...

Cheers,
H.
