The clearer way to do this in R, in my opinion, is to use the waitúLSE flag in system(), which has the same effect as & directly in the shell.

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?
