export variable from bash to R

Hi Barry,

I already tried adding print commands, but even if I put the print command
right under "myscript <- function()", there is no printed output in the
shell...

If your script is just:

 myscript <- function(){
   # some stuff
 }

Then all it is doing is defining a function. It won't actually call
the function unless you call it with something like:

 myscript()

after you've defined it.

Or you could just not bother wrapping the code in a function at all.
