R devel - Apr 2008 - __FILE__ for R

I've often missed the ability to get the directory of the currently
running script.  It's actually been possible for a while:

FILE <- (function() {
  attr(body(sys.function()), "srcfile")
})()

thanks to Duncan's recent changes to file parsing.  This is pretty
useful for sourcing in files relative to the current script, rather
than the working directory.

Sorry, that should be:

FILE <- (function() {
  attr(body(sys.function()), "srcfile")
})()$filename
