LaTeX generally doesn't work well with spaces in filenames.  I'd save 
the graphic in the same directory as the .tex file (or a simple 
subdirectory of it, say "figs") and then use an include like

\includegraphics{Density.eps}

or

\includegraphics{figs/Density.eps}

As Ray said, this is probably a pdflatex issue.  Unfortunately, latex 
can handle eps but not pdf, and pdflatex can handle pdf but not eps. 
This is why Sweave produces both by default.  If you do the same, then 
you could use

\includegraphics{Density}

with no extension, and both systems would look for extensions they 
recognize.
