All, I've encountered the same problem as others who have posted under the same subject.
I've had R-1.8.1 installed and running since it was released. Yesterday morning when I tried to start Rgui.exe I got the subject error message. Since I live at the whim of the network administrators I can only assume it was a recent MS critical update. I tried installing R-1.9.0 but no joy. I created ".Renviron" with HOMEDRIVE and HOMEPATH values set appropriately (see bat file below) but this did not solve the problem either. The following did work: Create batch file MyRBat.bat ---start--- SET HOMEDRIVE=D: # for some reason "echo %HOMEDRIVE%" returns "C:" even when I set the install path to D:\{HOME}\ SET HOMEPATH=\Documents and Settings\vinyardwc\My Documents\Rwork\work Rgui.exe ---end--- Cheers [[alternative HTML version deleted]] ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
