Hi, I want to use the .RProfile to set defaults such as text editor. Is this a file I need to create? Also, where should I put it? I tend to create .RData files for different projects, putting each in a different Windows (Vista) folder. Is one .Rprofile file created that any instance of R can access (I would imagine so)? Thanks, Walt -- ________________________ Walter R.
