In lattice, using the command trellis.par.get for superpose.symbol, plot,
symbol and/or dot.symbol shows that we can specify alpha, cex, col, fill
(for  superpose.symbol and plot.symbol), font, and pch.  Trial and error
shows that the font affects letters but not pch=1 or pch=3 (open circles
and plus signs.) I want to use open circles and plus signs, keep the colors
and cex  I've specified but make the symbols bolder, much the way a
higher lwd makes lines bolder.  Does anyone know of a library that
does that or can anyone think of a workaround to make the markers
stand out better without making them larger?

I'm using R2.8.1 with Windows Vista.

Thanks,

Naomi
