I do not have any experience with use of (bash) shell scripts under
Windows. Sweave.sh can be used with Cygwin, but I am not sure how to use
shell script without Cygwin. I noticed that some "scripts" in R*/bin
directory on our Windows machine are perl (build, check, INSTALL, ...)
and shell (Rd2dvi.sh, Stangle.sh, Sweave.sh, ...) scripts. This
therefore means that R ships also perl and shell interpreter or am I
missing something?

We don't ship Perl or sh.exe, but we do describe how to get them in the
R Admin manual.

Maybe I got this totally wrong. Say someone who uses Windows finds R and
installs it via setup file. Can he/she launch the folowing without
having Perl and/or sh.exe?

R CMD script whateverOption

No.  Installing a binary package has a pure R implementation so it
doesn't need R CMD, but most of the capabilities of R CMD are not
available with a basic R install.

Can you just clarify what the dependencies are for

Rcmd sweave

where Rcmd is the Rcmd command distributed with R that is run
from the Windows command line.   Does that require perl or other
tools to run?

That needs sh.exe, not Perl.  But it's just the equivalent of

 echo "library('utils'); Sweave('filename')" | Rterm --no-restore --slave

at the command line or

 Sweave("filename")

in a standard R session.

Thanks for the explanation.  I could look into replacing Rcmd with the Rterm
pipeline in the sweave.bat script to eliminate the sh.exe dependency so
sweave.bat can be used with a basic R installation.
