Hi Vitalie,

   First of all, thank you very, very much for your answer. Since there 
were no answer to my question I thought that I had disturbed the mailing 
list (I thought it was not the good place for my question) and I was a 
little confused !

For my problem, I finally understood that reftex requires the file name 
to end with .tex whereas latex works with \input command 
(\input{file.tex} works) but not with \include command 
(\include{file.tex} doesn't work). So, I decided to work only with the 
\input command giving the name of the file with the .tex extension. If I 
have to use the \include command I write it twice :
\include{file} : in order to include the file
\include{file.tex} : it doesn't include the file but reftex works.

I set the variable reftex-file-include-commands to ("include" "input" 
"SweaveInput") as you say, and the variable 
reftex-toc-include-file-boundaries to t in order to see the names of 
every slave file in the TOC, I find that is very convenient.

All work fine when I am in the master file but when I am :

1. in a .rnw file, C-c = shows only the sections of the .rnw file :

  File testrnw.rnw starts here
      1 section 1 testrnw.rnw file
  File testrnw.rnw ends here

The end of my testrnw.rnw file :

%%% Local Variables:
%%% TeX-master: "masterfile.rnw"
%%% End:

2. in a .tex file, C-c = shows all the sections of every slave file but 
the variable reftex-toc-include-file-boundaries doesn't work for the 
.rnw files. There is no longer the sentences : "File testrnw.rnw starts 
here" and  "File testrnw.rnw ends here" but we see the sections.


Also, don't forget to type r to refresh the toc in the toc buffer to see 
the good result of the C-c = command during the tests !

Thanks,
Laurent
