Sweave scatterplot dots not appearing in LaTeX output

[MaxManus]

I'm trying to use R and Sweave to make a document. This gives the Latex;
\documentclass[a4paper,norsk]{article}
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{babel,textcomp}
\title{test}
\author{me}
\usepackage{Sweave}
\begin{document}

\begin{Schunk}
\begin{Sinput}

\end{Sinput}
\begin{Soutput}

Max. :134.00 Max. :13.00
\end{Soutput}
\end{Schunk}
\includegraphics{test-003}

\end{document}

When I try to run Latex with MikTex it gives me a empty plot. Does anyone know why?

Edit: It seems like it's the "dots" in the scatterplots that are the problem. The finished latex document shows lines, but not dots. Does anyone know what to do?

I used pdflatex to compile in MacTeX--TeXwork's (which I believe is also the default for MikTeX) built-in PDF reader garbles your graphic, but Acrobat Reader seems to render it just fine.

Thanks, it showed in Acrobat
