[R] multiple plots

[Chuck Cleland]

How about this:

myframe <- expand.grid(p1 = rnorm(10), p2 = rnorm(10),
                        classes = paste("class", 1:10, sep=""),
                        colors = c("blue", "red", "green", "yellow", 
"orange", "purple"))

library(lattice)

xyplot(p2 ~ p1 | classes * colors, data=myframe)

If you want the 60 panels on more than one page, see the layout argument 
to xyplot.  For example,

xyplot(p2 ~ p1 | classes * colors, data=myframe, layout=c(6,5,2))
