I have installed Sweave as recommended.
http://lifeasclay.wordpress.com/tag/sweave/. Placing a test.Rnw file, for
instance, in
"/Library/Frameworks/R.framework/Versions/2.15/Resources/library/utils/Sweave"
generates test.tex files that generate pdf files with LaTeX. To be honest,
placing Rnw files seem to make sense. The "exams" package does require not this
step. It uses texi2dvi and other tools to accomplish this result. Since I have
a cursory knowledge of Mac OSX and the role that texi2dvi plays, I cannot
understand the error message obtained below. The error occurs when executing
the Example from R help(exams).

Error in texi2dvi(out_tex[j], pdf = TRUE, clean = TRUE, quiet = quiet) :
Running 'texi2dvi' on 'plain1.tex' failed.
I am running:
R version 2.15.1 (2012-06-22) -- "Roasted Marshmallows"
Copyright (C) 2012 The R Foundation for Statistical Computing
ISBN 3-900051-07-0
Platform: i386-apple-darwin9.8.0/i386 (32-bit)
and Mac OSX Version 10.8.
After submitting the above to r-help-request "12. texi2dvi error
"Sweave" and "exams" (Paul Ossenbruggen)", I delved further into the problem
and discovered the source of the problem:
> exams(file = "tstat.Rnw", quiet = FALSE)
Writing to file tstat.tex
Processing code chunks with options ...
1 : keep.source term hide
You can now run (pdf)latex on tstat.tex
Error in texi2dvi(out_tex[j], pdf = TRUE, clean = TRUE, quiet = quiet) :
Running 'texi2dvi' on 'plain1.tex' failed.
Output:
You don't have a working TeX binary (tex) installed anywhere in
your PATH, and texi2dvi cannot proceed without one. If you want to use
this script, you'll need to install TeX (if you don't have it) or change
your PATH or TEX environment variable (if you do). See the --help
output for more details.
For information about obtaining TeX, please see http://www.tug.org. If
you happen to be using Debian, you can get it with this command:
apt-get install tetex-bin
Apparently, it is a simple matter to fix the error; however, I don't
have sufficient knowledge to know how to proceed.
I installed LaTeX using TeX Live and use TeXShop as my LaTeX driver. A
bibtex folder is stored on the path /library/texmf but TeX is not. I suspect
that I must install TeX in this folder but again unsure.
Any help will be greatly appreciated.
Thanks,
Paul
