Hi all, Is it possible to tell whether someone is using the R GUI or the command line programmatically? Hadley

Yes. If you're literally interested in the R.app GUI
Sys.getenv("R_GUI_APP_VERSION")
will be a real number (non-empty check should do).
If you want to know whether you're running in some GUI with Aqua
support (the R GUI is one of them, but it could be others, too), you
can use
.Platform$GUI=="AQUA"
This may, however, change in the future as we generalize AQUA-specific
features into core R.
Cheers,
Simon

Great - thanks. It's for a package where the user needs to be able to abort a long-running computation (an animation) and we're trying to give them correct cross-platform/gui instructions for doing so. Hadley
