I'm trying to learn Sweave. So far things are going well with the chunks of
code identified by << >>=
But I'm having trouble with the in-line text use of \Sexpr.
Here is a short example .Rnw file:
\documentclass[12pt]{article}
\usepackage[margin=1.25in]{geometry}
\usepackage{graphicx}
\usepackage{Sweave}
\begin{document}
<<test>>=
pnorm(1)
@
\Sexpr{2+6}
\end{document}
The .tex file that it yields contains
\Sexpr{2+6} as its next-to-last line. \usepackage{Sweave} is in its preamble.
When I pdflatex that file, the resulting pdf file shows the proper value of
pnorm(1), but it does not contain "8" near its end. Instead it contains "2+6".
I had expected the computed value.
Also, pdflatex gives me a message that "there was an error opening the
document. The file cannot be found." I have to go find it and open it, instead
of it opening automatically like a non-problematic case would.
Running R 2.5.1 on WinXP, with MikTex.
Any advice? Thanks.
