[R] Using summaryBy with weighted data

Hi everyone,
I am trying to run Sweave.bat (batchfiles_0.6-1) from the command line 
on Windows, but I get this error:

C:\batchfiles_0.6-1>Sweave.bat Sweave-test-1
"Error: rterm.exe not found"

I don't know how to set up the path if this one were the problem... I 
ran rcmd.bat and I got this... so I don't know if it is a path problem.

C:\batchfiles_0.6-1>Rcmd,bat
R_ARCH=/x64
R_ARCH0=x64
R_ARCH0=x64
cmdpath=C:\R\R-2.12.1\bin\x64\Rcmd.exe
args=,bat
'bat' is not recognized as an internal or external command,
operable program or batch file.

the path of rterm.exe in my computer is: C:\R\R-2.12.1\bin\x64
thank you in advance!
