[R] plot via xyplot not being saved

[Benilton Carvalho]

Hi everyone,

it's been a while I've been trying to save a plot created via  
lattice:::xyplot

if I have a file tst.R with the following code:

y <- rnorm(100)
x <- rnorm(100)
z <- sample(letters[1:4], 100, rep=T)
library(lattice)
bitmap("tst.png")
xyplot(y~x|z)
dev.off()

and I source it, I get the tst.png file, which is a blank page.

If I copy and paste instead, I get the correct plot.

Any suggestion?

Thank you very much,

b
