[R] supplying dynamic main argument to plot?

[Richard M. Heiberger]

It is easy to control the main title with plot, but you will
get much better looking plots if you use xyplot.

library(lattice)
tmp <- data.frame(x=rnorm(100),
                  y=rnorm(100,4,2),
                  ID=paste("Patient", rep(1:5, rep(20,5))))
xyplot(y ~ x | ID, data=tmp)
