[R] Rdconv LaTeX files

[Michael O'Keeffe]

Hi,
I've written a package and converted my Rd files into LaTeX using
Rdconv. When I copy and paste these files in to my Sweave document I
get the error message when compiling the Sweave file:

! Undefined control sequence.
l.32 \inputencoding
                   {utf8}

I also get the error message for the "\HeaderA", "\keyword".
Additionally I get an environment undefined error for some of the
"\begin" control sequences. Do I need to specifically "include"
certain LaTeX libraries in my Sweave document?

Regards,

M
