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).
> library(exams)
Loading required package: tools

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

and Mac OSX Version 10.8.
Any help will be greatly appreciated.
Thanks,
