[R] thickness of boxplots

[Kenneth Roy Cabrera Torres]

Hi R users:

How can I obtain with bwplot boxplots with bwplot whose box width
will vary acording to other variable.

bwplot(categ1~continuos|categ2,box.ratio=continuos2,data=data.base)

But it doesn't work as I expected.

Thank you for your help.
