This is true in the regular environment, but should not be true for
code.  Think about all the special characters encountered in R code---
$, quotes, _ ^.  The following minimal document compiles fine on my
system:

\documentclass{article}
\usepackage{Sweave}
\begin{document}
\section{Example showing underscores works fine inside an Schunk}
\begin{Schunk}
\begin{Sinput}
data<-
read.csv("c:\\Users\\Daniele\\Desktop\\dati\\dati_england.csv",header=T,sep=",")
\end{Sinput}
\end{Schunk}
\end{document}

producing the attached PDF.

My system:

R Under development (unstable) (2011-08-13 r56733)
Platform: x86_64-pc-mingw32/x64 (64-bit)

Version 0.3 r.670 (MiKTeX 2.9)
