[R] Sweave Makefile issue

[Luc Villandré]

Dear R-specialists,

I am trying to create a Makefile that will first convert all my .Rnw 
files into .tex files and then, that will run the LaTeX compiler to 
produce a pdf document. This issue has been discussed before. Hence, 
I've basically adapted a Makefile I found at 
http://n4.nabble.com/R-Sweave-R-and-complex-latex-projects-td810020.html#a810023 
to make it compatible with a Windows XP environment. You will find my 
version of it at the end of this message.

However, it's not doing what I expect it to do. Instead of only using 
pdfTeX on "total_article.tex" (which is the file with the necessary 
headers and \include's), it tries to convert all my tex files into pdf, 
which of course cannot be done since only total_article.tex has the 
necessary structure to be understood by the compiler.

What's wrong then with this Makefile (I am using GNU Make 3.81)?

I will be grateful for any help you can provide.
