Error in generating sweave-tex -> pdf file

Should the Sweave package be in /usr/share/texmf/tex/latex/? How about
Sweave.sty?

Thanks

 Hi,
 I created a Sweave file (see below). when I want to convert tex
 file generated from it into pdf, I get error message as follows:

 >   texi2dvi("test.tex", pdf=TRUE)

 Error in texi2dvi("test.tex", pdf = TRUE) :
    Running 'texi2dvi' on 'test.tex' failed.
 LaTeX errors:
 ! Undefined control sequence.

The Schunk, Sinput, and Soutput environments are defined in Sweave package.
Something went wrong and latex didn't find them, either because it didn't find
Sweave.sty, or because it did, but that file has been messed up.

 test.Rnw

 \usepackage{Sweave}
 \ documentclass [ a4paper ]{ article }
 \ title { Sweave Example 1}
 \ begin { document }
 \ maketitle

Are there really spaces between the backslashes and the macros?  I think that
doesn't work.  You should also have the \usepackage{Sweave} line after the
opening \documentclass line.

 In this example we embed parts of the examples from the
 help page into a \ LaTeX {} document :
 <<a>>=
 y=2
 y = y +1
 @
 which shows that the location parameter of the Ozone
 distribution varies significantly from month to month . Finally we
 include a boxplot of the data :

 \end{ document }
