I'm not able to replicate using the same setup on several computers, either
with R.app or R running in the terminal, so it's likely something highly
specific to your setup. I'd suggest reinstalling or upgrading R and see if the
problem goes away.
The clearer way to do this in R, in my opinion, is to use the
wait=FALSE flag in system(), which has the same effect as & directly
in the shell.
Hmm, as documented, it actually appends & to the shell command for
you. Whether that is clearer depends on the reader, but wait=FALSE is
cross-platform.

I just encountered an odd problem with the system command; perhaps someone can
provide some insight.
At some point in the past (~ 6 months ago; I was using the latest version of R
and Snow Leopard available at the time), the command:
system("open -a /complete/path/to/app /complete/path/to/file &")
ran successfully.
I am using R 2.12.0 and OS X.6.6 and the command failed. To my surprise,
removed the ampersand fixed the problem. I don't know if the problem lies with
OS X or R's interaction with OS X. Does anyone have any insights into this?
