Dear RUsers, I just upgraded from 2.6.0 to 2.6.2 and tried to reinstall the RWinEdt patch to work with WinEdt so that I can continue function as I always have but I have run into problems that I don't understand how to fix.

Folks, The projection pursuit regression function in the base R seems to crash when the optimization level is set to zero, i.e. the initial ridge terms are accepted without refitting. I encountered this problem in an out-of-sample prediction exercise using predict. But further investigation suggests the issue is with the ppr fit and predict just sppeds up the crash. The other optlevels seem to be

Hi, I have a new computer with Windows Vista and I am trying to use RWinEdt, which I have always used. I am using R version 2.5. The installation of the RWinEdt library is funny. First, it didn't install at all. Then, I uninstalled/reinstalled both R and WinEdt, downloaded the package again from the CRAN repositary, got some error messages, but RWinEdt initialized. I closed R and WinEdt,

Usually when I open either one, the last files I was working on *with that program* are opened automatically. So if I last used mydoc.tex in WinEdt and myprogram.R in RWinEdt those
