If you have C:\Rtools\bin on your PATH note that it contains a UNIX-like find utility that conflicts with the find utility in Windows. If that is the problem then remove that from your PATH and then run the batch file. The batchfiles distribution at http://batchfiles.googlecode.com has utilities (Rgui.bat, R.bat, Rtools.bat, etc.) that will automatically add C:\Rtools\bin to your path temporarily or only while R is running so that you can leave it off your PATH.
I guess it's the use of system() rather than shell() that causes the problem. Under Windows, you have to use shell in order to start a command interpreter.

I was wondering if anyone else has noticed this and reported it before I submit a bug report. I noticed while running the RGui and attempting to debug one of my scripts that I encountered a Windows error informing me that "Find String [grep] Utility has encountered a problem and needs to close." It is being generated by a call to a DOS batch file which contains a call to Find.exe. It can be reproduced by simply typing "System("find")" in RGui. What I found strange is that I have been running this script daily without this problem for months. I now realize I never ran that portion of the script while in RGui.exe. It has always run in batch mode which is done by Rterm.exe. I have tried this on three separate machines now all running Windows XP SP3, with versions of R 2.8.1 and R 2.10.1 If executing "System("find") under RGui, an error window for the Find String Utility is generated and the command is not exectuted. If the same command is issued in Rterm the expected "FIND: Parameter format not correct" message is properly returned. It doesn't seem an important bug, but it could be the canary in the mine for a larger problem somewhere down the road.
