R help - May 2009 - locating rcmd.exe through a batch script

Dear R-sians!
The following command works fine on Dos Prompt, but not in a windows batch
script...

dir /S /B C:\Progra~1\R\R* |findstr /I "rcmd.exe" |findstr /I
"2.8.1"


how do I implement the above in a windows batch script? I tried to use:
for /F "usebackq tokens=*" %%i in (`dir /S /B C:\Progra~1\R\R*
|findstr /I
"rcmd.exe" |findstr /I "2.8.1"`) do @echo %%i

and it does not seem to work! Where am I doing wrong?


THANKS A TON in advance!

Regards,
Santosh

Dear R-sians...
Installing libraries through RCMD INSTALL does not seem to work.. Is the
following command c

R CMD install -l "C:\Program Files\R\R-2.8.1\library"
"C:\temp\xpose4_4.0.4_win32
.zip"

I get the following error message.
'C:\temp\xpose4_4.0.4_win32.zip':Windows binary packages in zipfiles are
not
supported: skipping
