R help - May 2011 - Weighted box or violin plots in Lattice?

Is it possible to create weighted boxplots or violin plots in lattice?

It seems that you can specify weights for panel.histogram() and 
panel.densityplot(), but not for panel.bwplot or panel.violin().

Please let me know if I've missed something in the package documentation.

Thanks!

Not for panel.histogram() either.

It's not immediately obvious how you would get weighted boxplots. For
weighted violin plots, it should not be too difficult to write your
own panel function generalizing panel.violin(); just pass in 'weights'
and 'subscripts', and get the per-panel weights inside the panel
function as weights[subscripts] (as in panel.densityplot).

The only difference is that densityplot() implements non-standard
evaluation for 'weights', which bwplot() does not, so you have to
specify 'weights' explicitly.
