[R] Troubleshooting sweave

[sachinthaka.abeywardana at allianz.com.au]

Hi All,

I've reproduced the example from Prof. Friedrich Leisch's webpage. When I
write sweave("Example-1.Snw") OR sweave("Example-1.Rnw"), (yes, I renamed
them). I get the following error:

Writing to file example-1.tex
Processing code chunks ...
 1 : echo term verbatim

Error:  chunk 1
Error in library(ctest) : there is no package called 'ctest'

Also while I'm at it, is there an R command to compile the tex file as a
pdf or does the Sweave() function do that for me?

Thanks,
Sachin
p.s. sorry about the corporate notice.

example-1.Rnw: from http://www.statistik.lmu.de/~leisch/Sweave/

In this example we embed parts of the examples from the
\texttt{kruskal.test} help page into a \LaTeX{} document:

<<>>=
data(airquality)
library(ctest)
kruskal.test(Ozone ~ Month, data = airquality)
@
which shows that the location parameter of the Ozone
distribution varies significantly from month to month. Finally we
include a boxplot of the data:

\begin{center}
<<fig=TRUE,echo=FALSE>>=
boxplot(Ozone ~ Month, data = airquality)
@
\end{center}
