In an Sweave slide, I want to use sem::read.moments() and
sem::specify.model(), which work
by using scan() to read the following lines, up to the first blank
line. However, Sweave
throws an error:
> Sweave("sem-thurstone.Rnw")
Writing to file sem-thurstone.tex
Processing code chunks ...
1 : term hide (label=arrests-setup)
2 : echo term hide (label=thurstone-data)
Error: chunk 2 (label=thurstone-data)
Error in sem-thurstone.Rnw:43:12: unexpected numeric constant
42: .828
43: .776 .779
^
Is there some switch or option for Sweave that will make this work?
Below is the slide in question in an executable example:
\documentclass[dvipsnames,pdflatex,compress,beamer]{beamer}
\usepackage{Sweave}
\definecolor{Sinput}{rgb}{1,0,0}
\definecolor{Scode}{rgb}{0,0,0.56}
\definecolor{Soutput}{rgb}{0,0,1}
\DefineVerbatimEnvironment{Sinput}{Verbatim}{formatcom={\color{Sinput}},fontsize=\footnotesize,baselinestretch=0.9}
\DefineVerbatimEnvironment{Soutput}{Verbatim}{formatcom={\color{Soutput}},fontsize=\footnotesize,baselinestretch=0.85}
\DefineVerbatimEnvironment{Scode}{Verbatim}{formatcom={\color{Scode}},fontsize=\small}
\begin{document}
\SweaveOpts{engine=R,height=6,width=6,results=hide,fig=FALSE,echo=TRUE}
