[R] short suggestion to the R development team

[Gabor Grothendieck]

In R 2.2.0 (it might be different in other versions) just put this
in your source file:

this.file <- parent.frame(2)$ofile

(If you place it into a function in your sourced file then will need
to increase the number 2 to take into account of the extra call.)

(ala \jobname in latex.)  if this is difficult, would it be easy to introduce something like "$0" in perl (i.e., argv[0] in C), which contains the current R file?  I just checked what perl does interactively, when no file is being processed.  It fills $0 with "-", though it would seem to me that just "" would be more appropriate.
