a vectorized solution can be rendered smoothly at any desired size. Furthermore, it can be easily edited and the size of the file is (usually) much smaller than the bitmap version. No overkill at all, as it is SIMPLER to use the vector version.

Hmmm, i've downloaded your pdf, and it is clearly ugly at 400%. I'm talking about the Rlogo.pdf file. E.g. i'm not sure that it would look good on an A0 poster.

Maybe this is different if you use Sweave. pdflatex itself handles jpg without problems.

Of which the conclusion is that there is no vector version.
