I presume that R is running in a UTF-8 locale on your Debian box (or
some other locale that is different to the one pdflatex is working in);
the fancy quotes used in some print methods in R aren't available in all
locale/font encodings and these get interpreted as the "gibberish" you
are seeing.

Stick this in your preamble and see if it works (you might need to
install a TexLive package from your usual Debian repository to get this
[LaTeX] package installed):

\usepackage[utf8x]{inputenc}

it did for me on my Fedora box when I first came across this issue.
