You need to either dynamically generate the entire final .tex file including
the preamble and so forth via your function(s)
or:
alternatively use a .Rnw Sweave "master" file template that contains the static
content and then in that file, insert the dynamic content using one or more
directives along the lines of \input{InsertContentHere.tex}, where
InsertContentHere.tex contains raw TeX content to be inserted at that point in
the master file when processed by Sweave.
The content of the *.tex files can be generated via various R functions
including ?cat for raw text and others like the xtable() function in the CRAN
package of the same name or the latex() function in Hmisc, which can be used to
create tables, etc.
Note that the content of InsertContentHere.tex will not itself be processed by
Sweave, as if it was a "child" .Rnw file. If you want that type of
functionality, you would need to use \SweaveInput{InsertContentHere.Rnw}.
Once you have your final .tex file, you can then run pdflatex on that file via
?system.
