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.

You shouldn't be placing your .Rnw file in that directory.
What do you mean by "seem to make sense"?

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).

You probably mean ~/Library/texmf.
No TeX does not get installed in that directory.

Did you download MacTeX.pkg from www.tug.org?
Without information about what you downloaded and what you did it's difficult to to tell you how t o proceed.
