hi, I try to configure my system so when I click on an .R script, the script is executed in the R GUI. I tried to open .R files with different .exe files that I found in the bin-folder of the R folder (R.exe, Rcmd.exe, Rgui.exe ...). But I always get the message; ARGUMENT 'c:\...\...' ___ignored___ (where c:\...\.. is the path to the .R file) how can I change this behavior? Sorry I am not so familiar with windows OS (I use windows xp). thanks for any help!
