R help - Oct 2008 - a question about diparate device quality

List,

I have a question about why plots sent to certain devices can be of so much
worse quality than others.  Whenever I plot to x11 or pdf the graphs are of
excellent quality.  eps is a bit poorer, but of passable quality, and jpeg
or tiff are terrible.  I tried all manner of parameters, on many versions
of R (most major releases from about 2.2 - present) under linux and windows
and on a few different (pc) hardware setups and this patterns seems to be
invariant.  Could anyone explain why this is the case?

For school and work I just pdflatex my pdf graphs into latex so it isn't a
problem, but my new job likes to include them in, say, MS word documents for
which I cannot easily use pdf.

TIA,

Kyle
