'ctest' was a package that was merged into the 'stats' package in R version
1.9.0, which was released back in 2004. So it would appear that Fritz (cc'd
here) has not updated the examples to reflect that change.
A simple fix would be to remove the 'library(ctest)' line from the file.
If you look at:
require(utils)
?Sweave
there are some examples of using both internal and external R commands to
process the file into a PDF. Sweave itself just generates the TeX source file
(.tex), which then requires a LaTeX installation to process that file into the
PDF (or EPS as may be required).
I would also be sure to review ?RweaveLatex for more information, including
some potential environment issues that you may have to address in the Details
section. Fritz' Sweave FAQ and manual on his site are also good references as
may be required.
Presuming that you have LaTeX installed on your computer, the easiest thing to
do may to use:
pdflatex YourFileName.tex
at the command line, to process the resultant TeX file into a PDF. The steps
can be a bit more complicated if you are using any LaTeX packages that might
require the intermediate creation of a DVI and PS file. That would include
packages such as PSTricks, etc.
