That depends on the kind of graph. I aggree that you should try
vector at first. But when it generates very larges files (e.g.
scatterplots with thousands of points) then you better switch to
bitmaps like tiff or png. Jpeg can create artefacts, so is not very
good for graphics.
True. Sometimes one can get away with switching from a normal
scatterplot to hexbin or something like this but if that is not
anoption a high resolution tiff or png is the way out.
And of course, I agree that jpeg should never be used for graphs.
That depends on the definition of 'graphs'.
One reason that I added jpeg support to Sweave is that some of us do
work in areas where figures (and it is 'figures' you put in papers in
my native language) are images, even photographic images.
