reading .Rprofile at startup in R 2.0.0
You wouldn't find info on setting environment variables in the R FAQ because environment variables are an operating system feature. Under recent versions of Windows, environment variables are stored in the Registry and can be set persistently through a dialog. In Windows XP, this is found under My Computer; Properties; Advanced; Environment Variables. I would set a User, rather than System, variable; it matters only if more than one user on your PC is making use of R and they want different profiles. As you say, unless you are familiar with this, it could be easier just to move the file. The advantage of using an environment variable is that you can put the file where YOU want it. To most folks, that is a non-issue. Some of us however are determined to bend computers to our wills, rather than the other way around. We frequently fail but keep trying. Regards, MHP

Thanks for the hint. Having got through the "CHANGES" file as advised by Pr Ripley (I unfortunately checked first the "NEWS" file and forgot that one..) I found it may be more simple (to me) to put the .RProfile file into the "my documents" directory. It works fine now. Setting environment variables is probably easy when one knows exactly which file to manage with and where it is... which is not the case to me yet (even after having read carefully the rw-FAQ 2.13).

Dear listers, Moving from R 1.9.1 to R 2.0.0 today, it happens that the "traditional" .RProfile (located in my home directory: C:\Documents and Settings\Giraudoux) is not read at startup with R 2.0. Any suggestion? Patrick Giraudoux
