R help - Apr 2004 - Sweave in makefile under Win XP

Hi all.
 
To automate the production of a document I want to have something like:
 
test.tex : test.Rnw
    "Sweave("test.Rnw") "| R  --no-restore --no-save
 
in a makefile.
 
This however gives an error as R states: Sweave("test.Rnw") : not
found.
 
I use R-1.9.0pat (040424 I think) on Win XP.
 
Any suggestions, hints or plain help appreciated.

If that's what you did, I don't think R ever saw it. The shell would
think that you were trying run a program called "Sweave(test.Rnw) ".
If you want to pipe the string to R, you need at least an "echo" in
front of it. Also beware that the quotes as written don't match up the
way I think you think they do.

echo "Sweave(\"test.Rnw\")"| R  --no-restore --no-save
  
should be more like it. Notice that you need to start the line with a
TAB inside a makefile, not 4 spaces (or did your email program just
mangle it?).

Look at the examples in the makefiles in the R sources, and beware of 
shell quoting.  So

echo "Sweave('test.Rnw')" | Rterm.exe  --vanilla --slave

may be the simplest.  (I would avoid using `R' in programming as it may 
well find the wrong thing one day.)
