Trellis Histogram

Multiple plots can be placed into a single plot using the lattice package. Here we also illustrate the use of the color option of the histogram function, setting it to FALSE to obtain a transparent background.

library(lattice)
load("wine.Rdata")
trellis.device(width=7, height=5, new=FALSE, color=FALSE)
