[R-SIG-Mac] Scripting R

[Christian Prinoth]

Hi,
 is there something similar to rcom on OSX? I understand that R for OSX
has some limited applescript support, but I was wondering if there is an
easy way to share data with other applications. My ultimate goal would
be to use R together with a spreadsheet as I can currently do on windows
with R, rcom and Excel.

Thanks
