[R] several boxplots or bwplots into one graphic

[Christoph Lehmann]

Hi
I have 10 variables and 2 groups. I know how to plot a bwplot for ONE 
var. e.g.

var.a var.b var.c .. GROUP
0.2   0.5   0.2   .. 0
0.3   0.2   0.2   .. 0
..
0.1   0.8   0.7   .. 1
0.5   0.5   0.1   .. 1
..


bwplot(var.a ~ GROUP, data = my.data)

How can I plot 10 bwplots (or boxplots) automatically into one graphic? 
is there any function from lattice which can do this?

thanks for a short hint
