You can specify height and width as arguments to the code chunk or set
new defaults with something like
\SweaveOpts{width=5,height=3}
(I think those measurements need to be given in inches; I don't think
there's a way to use an expression like unit(80,"mm").)
You can also control the size of the plot in the final document with
LaTeX code like
\usepackage{graphicx}
\setkeys{Gin}{width=3in}
and then the LaTeX rules for handling units would apply, so 80mm is fine
instead of 3in.
