[R-SIG-Mac] Shortcut for launching command line R?

[Simon Urbanek]

That seems a bit convoluted to me. For a clickable document you can simply create R.command containing single line
R

If you want an app, just open the Automator, pick Application type, select "Run Shell Script" with single line
open -a Terminal /usr/bin/R

Cheers,
Simon

Although it is not particularly difficult to launch terminal application and then R from the prompt, it would be nice to have an icon on the dock to launch the command line R with one click.

There was a need for some ”fine tuning” to deal with problems of Terminal app scripting without manually changing preferences of Terminal app (problems include that in certain cases more than two windows are created instead of one and that it is not trivial to close (only) the correct window after quitting R under the default settings of terminal).

Created app works just like any other Mac OS X application and you can drag it to the dock to get the functionality to launch command line R with one click.

It is also likely that there are better, safer and more portable ways to provide such a functionality (across Mac OS X versions), but at least the basic idea can be tested with the script above.
