[R] Plot using treatment letter as points

[Greg Snow]

xyplot is a lattice plotting command, text is a base plotting command.  The 2 types don't play well together without extra work.  The base command plot with text is probably the easiest, or you can just use plot and pch:

> with(iris, plot(Sepal.Width, Sepal.Length, pch=c('s','e','i')[Species] ) )
