When I create a file describe.Rnw as follows:
\documentclass{article}
\begin{document}
<<results='asis'>>=
require(Hmisc)
latex(describe(cars), file="")
@
\end{document}
and try to compile it with
library(knitr)
knit2pdf("describe.Rnw")
I get error messages that suggest the latex created by the latex(describe()) combination has grammatical errors:
LaTeX errors:
P:/r/ellisp/test/describe.tex:65: LaTeX Error: Environment spacing undefined.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help
Your command was ignored.
P:/r/ellisp/test/describe.tex:131: LaTeX Error: \begin{document} ended by \end{
spacing}.
See the LaTeX manual or LaTeX Companion for explanation.
I can see the latex it has generated, pasted below - something wrong perhaps with the line spacing confusing the parsing? My whole setup is new (in fact in testing mode) and I'm new to knitr although I've successfully compiled documents, but I don't know whether there may be something wrong with my setup too. My first question is, am I doing something wrong or is this a more general problem??

Since the spacing environment is undefined, add
\usepackage{setspace}
