[R] Pretty onscreen plots?

[Charles Annis, P.E.]

I find the Windows metafile works quite well if you size the graphic in
R before right-clicking and copying as a metafile.  Resizing in
PowerPoint sometimes produces undesirable font characteristics.  Getting
the size and aspect ratio the way you want it in R, by dragging the
grapic's edges, avoids that.

I use PDF and make my presentations in PDF using pdflatex, or even in
postscript and Distiller.  That way the final document has vector
graphics, and bitmapping only occurs at the very last minute, when the
projector resolution is known.

In theory win.metafile should do the same for powerpoint, but in
practice
it is not as good.  Probably the metafile graphics driver could be
improved ....
