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.

Hi,
this works for me (R 2.5.1, Linux):
<<echo=false>>data(airquality)
library(ctest)
kruskal.test(Ozone ~ Month, data = airquality)
@
Wir haben hier also \Sexpr{nrow(airquality)} Datenzeilen in airquality.
This works
\Sexpr{2+6}
I think the error is in your latex setup, not in R or Sweave.

Thanks.How did you produce the .tex file? I just cut and pasted your file into test.Rnw, and Sweave( "test.Rnw" ) produced the .tex file shown below, with no 2+6 in it. \documentclass[12pt]{article} \usepackage[margin=1.25in]{geometry} \usepackage{graphicx} \usepackage{Sweave} \begin{document} \begin{Schunk} \begin{Sinput} > pnorm(1) \end{Sinput} \begin{Soutput} [1] 0.8413447 \end{Soutput} \end{Schunk} 8 \end{document}
Duncan--
The .tex file that you describe as output of Sweave("test.Rnw") is
what I had expected. But I get this .tex file when I run Sweave:
\documentclass[12pt]{article}
\usepackage[margin=1.25in]{geometry}
\usepackage{graphicx}
\usepackage{Sweave}
\begin{document}
\begin{Schunk}
\begin{Sinput}> pnorm(1)
\end{Sinput}
\begin{Soutput}
[1] 0.8413447
\end{Soutput}
\end{Schunk}
\Sexpr{2+6}
\end{document}\documentclass[12pt]{article}
\usepackage[margin=1.25in]{geometry}
\usepackage{graphicx}
\usepackage{Sweave}
\begin{document}
\begin{Schunk}
\begin{Sinput}> pnorm(1)
\end{Sinput}
\begin{Soutput}
[1] 0.8413447
\end{Soutput}
\end{Schunk}
\Sexpr{2+6}
\end{document}
I think some inadvertent cutting and pasting may have made my last e-mail
difficult to interpret. Here is the .tex file I get as output of Sweaving my
.Rnw file. Note that "\Sexpr{2+6}" appears where you get (and I
want) simply "8".
\documentclass[12pt]{article}
\usepackage[margin=1.25in]{geometry}
\usepackage{graphicx}
\usepackage{Sweave}
\begin{document}
\begin{Schunk}
\begin{Sinput}> pnorm(1)
\end{Sinput}
\begin{Soutput}
[1] 0.8413447
\end{Soutput}
\end{Schunk}
\Sexpr{2+6}
\end{document}
Just goes to show, it helps to search the archives! I discovered this in the R-help archives: https://stat.ethz.ch/pipermail/r-help/2004-July/053920.html And similarly, in the Sweave manual: "A.16 After loading package R2HTML Sweave doesn?t work properly! Package R2HTML registers an Sweave driver for HTML files, and after that the Syntax for HTML is in the search list before the default syntax. options(SweaveSyntax="SweaveSyntaxNoweb") or calling Sweave like Sweave(..., syntax="SweaveSyntaxNoweb") ensures the default syntax even after loading R2HTML.A.16 After loading package R2HTML Sweave doesn?t work properly!

I use Tinn-R for my work, set up as per its instructions, so that when I open R, Tinn-R automatically opens, and in the process, it apparently loads R2HTML. So this explains my problem. Does anyone know where I should put "options(SweaveSyntax="SweaveSyntaxNoweb")?" For what command is this an option?
