It would be helpful to attach the .Rnw SWeave file (if small) or post it someplace that we can look at it, along with any data to replicate your process.

I took the EPS file that you provided here, included it in a simple tex file (test.tex) which contains the following:

\documentclass{article}
\usepackage{graphicx}

\begin{document}

\begin{figure}
    \centering
    \includegraphics[width=0.8\textwidth]{Report-fig1}
    \caption{Test Figure}
\end{figure}

\end{document}


I then processed the file using MacTeX (TeXLive on Snow Leopard) with:

latex test.tex
dvips test -o test.ps
ps2pdf test.ps test.pdf

The result is attached here and there were no problems.

I would say that perhaps your GS installation might be corrupted, but that seems less likely on two separate platforms, unless your installation process is common and faulty. Alternatively, there is a problem with your .Rnw file content, since that would be common on both.

That does not give you a specific resolution, but at least suggests that the EPS generation process via SWeave is not at fault.
