[R] Problem with bwplot

[Ernesto Jardim]

Hi, 

I'm ploting some box-and-whisker plots with bwplot but I'm not getting
any box-and-whiskers ... just dots.

I'm using lattice 0.9-16 with R 1.9.1.

Try

library(lattice)
rnorm(60)->vec1
rep(1:3,20)->vec2
rep(LETTERS[1:2],30)->vec3
bwplot(vec1~vec2|vec3)

Thanks

EJ
