[R] Sweave and \input or \include LaTeX commands

[Gabor Grothendieck]

If this were supported it should have a different command than the 
latex one or else one would not be able to do it at the latex level.
One might want to do it at the latex level rather than the Sweave
level in the case that one wants to have a vignette pass R CMD CHECK
but the vignette depends on software that is not generally available
or perhaps the vignette involves a large computation which would
otherwise impact every run of R CMD CHECK.  In these cases the portion
of the vignette that depends on the unavailable software or large
computation could be preprocessed using Sweave and then included
at the latex level to get by R CMD CHECK.

:  1 : echo print term verbatim
:  2 : echo print term verbatim
: 
: You can now run LaTeX on a.tex 
: 
: When you run Sweave on a.Rnw it founds only two chunks of R code. So it
: does not go into a1.Rnw i.e. it does not follow \input command. This 
: would be very usefull if one has such hierarchies in documents. Afcourse
: one can use Sweave on a.Rnw and a1.Rnw and then run LaTeX, but it would be
: nice if just one Sweave would do Sweave job for all files i.e. the same
: as LaTeX does.

: Hello!
: 
: I was just wondering if Sweave can work with \input or \include 
: LaTeX commands. So, is it aware of such a possible hierarchy in
: documents. I would test that, but I don't have such a report 
: available at the moment.
: 
: I thought of that when I was writting shell script for Sweave
: from command line and I have solved that part there.
