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.
