Hi, here's an obscure question someone can hopefully help with.
I have some R code that uses stuff from parallel (now a part
of the R core in 2.15 I believe), especially clusterApply.
However, this seems to cause problems in R.app, and I've
seen advice to not use these multicore functions, e.g. doMC,
in R.app.
So, I want to make this optional. How can have a program
check whether or not it is running in R.app or regular R?
Thanks so much for your help!!

PS: I saw this:
http://stackoverflow.com/questions/2020790/r-script-determine-whether-the-script-is-run-in-the-gui-or-from-command-line
Which says to use:
interactive()
...but that doesn't work. Interactive R is fine (e.g.
starting R from Mac Terminal), only R.app is not.
.Platform$GUI will be different in the two cases: "AQUA" for R.app and
something else in other cases. I don't know if that's a good test to
find out if clusterApply is safe.
