[R] line widths of plotting symbols in the lattice

[Stephen Tucker]

Dear List,

Sorry, this is very simple but I can't seem to find any information regarding
line widths of plotting symbols in the lattice package.

For instance, in traditional graphics:

> plot(1:10,lwd=3)
> points(10:1,lwd=2,col=3)

'lwd' allows control of plotting symbol line widths.

I've tried looking through the documentation for xyplot, panel.points,
trellis.par.set, and the R-help archives. Maybe it goes by another name?

Thanks in advance,

Stephen
