[R] Sweave in 2.13.1

[BXC (Bendix Carstensen)]

I run Windows XP.

and in a command window I get:

> c:\stat\r\R-2.13.1\bin\i386\Rcmd Sweave Lexis.rnw
Error in length(arg) : 'arg' is missing
Calls: <Anonymous>
Execution halted

AND:

> c:\stat\r\R-2.13.1\bin\i386\Rcmd Sweave --help
Error in length(arg) : 'arg' is missing
Calls: <Anonymous>
Execution halted

BUT:

> c:\stat\r\R-2.13.0\bin\i386\Rcmd Sweave --help
Usage: R CMD Sweave file

A simple front-end for Sweave

Options:
  -h, --help     print this help message and exit
  -v, --version  print version info and exit

Report bugs to <r-bugs at r-project.org>.

Same probelem for help on Stangle, but not for any other command.

Is this a bug or some new facility I overlooked?

Best regards,
Bendix
