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.
