[R] Sweave produces gibberish instead of apostrophe in pdf

[Prof Brian Ripley]

These are not 'apostrophe's: it's (that is an apostrophe) misleading to 
call them that.  They are single quotes, and there are two sorts if you 
look carefully.

Probably you are using a UTF-8 locale and not telling LaTeX (or us) so. 
There are several ways to do so, depending on the age of your LaTeX setup.

\usepackage[utf8]{inputenc}

is one.

Alternatively, you can tell R not to use UTF-8 quotes with 
options(useFancyQuotes=FALSE).

Please note the 'at a minimum' information the posting guide asked you 
for -- it included the locale.
