[R] how to use \Sexpr{} with sweave

[cryan at binghamton.edu]

Just goes to show, it helps to search the archives!

I discovered this in the R-help archives:

https://stat.ethz.ch/pipermail/r-help/2004-July/053920.html

And similarly, in the Sweave manual:

"A.16 After loading package R2HTML Sweave doesn’t work properly!

Package R2HTML registers an Sweave driver for HTML files, and after that the Syntax for HTML
is in the search list before the default syntax.
options(SweaveSyntax="SweaveSyntaxNoweb")
or calling Sweave like
Sweave(..., syntax="SweaveSyntaxNoweb")
ensures the default syntax even after loading R2HTML.A.16 After loading package R2HTML Sweave doesn’t work properly!

I use Tinn-R for my work, set up as per its instructions, so that when I open R, Tinn-R automatically opens, and in the process, it apparently loads R2HTML.  So this explains my problem.

Does anyone know where I should put "options(SweaveSyntax="SweaveSyntaxNoweb")?"  For what command is this an option?

Thanks.
