[R] Using sweave

[Matthieu Cornec]

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
