R help - Jan 2010 - Calling FING.EXE under RGui.EXE for windows.

This is sort of a strange bug.  Not show stopping, but annoying.  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.

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.
