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.

"[W]hen people thought the earth was flat, they were wrong.
When people thought the earth was spherical, they were
wrong. But if you think that thinking the earth is spherical
is just as wrong as thinking the earth is flat, then your
view is wronger than both of them put together."
