So, to be clear, your graphic is saved on the C drive.

And LaTeX is looking on the R drive.  Not quite sure how to fix this as you
did specify C:/xxx/Density.eps in your call to \includegraphics{}.  TeX and
LaTeX were developed in UNIX environments where there are no C drives or R
drives that segment the file system-- everything is contained under "/". 
There may be some special way you have to enter Windows paths.

You said you were using TeXworks which uses pdflatex as the default
compiler.  pdflatex compiles directly from .tex to .pdf and supports a wide
variety of graphic inputs *EXCEPT* for .eps as the warning message above
indicates.  The older method of compiling LaTeX documents is to use the
latex compiler which produces a .dvi file, then running dvips to produce a
postscript file and then running ps2pdf to produce a pdf file.  The latex
compiler *ONLY* supports .eps as a graphic input.

Personally, I would stick with the pdflatex compiler and switch to using the
pdf() device in R for your graphics output.

Hope this helps!
