R help - Feb 2005 - Using sweave

hello,

Suppose in Rnw file, I compute a numeric of name x containing the value 1.
In my tex file, I want to write 

Let x= "the real value of x"
so that I can see in my dvi file : Let x = 1,
with 1, the actual value of x written in a math environnement for example.

Thanks,

Matthieu

I believe you want \Sexpr{}

for instance:
let $x = \Sexpr{x}$

or if you need rounding
let $x = \Sexpr{round(x, dig=4)}$

Try the \Sexpr{} command in LaTeX (see the Sweave manual). It's OK for
a scalar.

For example, something like this in the body of your LaTeX file should
do what you want:

<<>>x<-1
@

Let $x=\Sexpr{x}$
