Re: [R] lattice: two grouping variables, one controls 'col', the other 'pch'

Thanks, that does the trick. I guess with two grouping variables it is 
best to bypass 'groups' entirely.'

 Currently, both color and plotting symbol change with the grouping
 variable g1. What is the best way to have color change with g1, but
 plotting symbol change with g2 (or vice versa)?

 Thanks,

Another option is to use ggplot:

install.packages(ggplot)
library(ggplot)
qplot(x, y, facet=. ~ f, size=g1, colour=g2)

Re: [R] lattice: two grouping variables, one controls 'col', the other 'pch'

Currently, both color and plotting symbol does not change with the
grouping variable g1, that is, when
g1-rep(5:8,each=64)
,plotxy still generates same plot.

subscripts argument is useful for your purpose.

see:
panel section and details in
 ?xyplot

try:

plot-xyplot(y~x|f,
 groups=g1,
 panel=function(x,y,subscripts,groups,...){
   
panel.superpose(x,y,subscripts,groups,pch=g2[subscripts],col=g1[subscripts],...)
 })
