[R] Impaired boxplot functionality - mean instead of median

Hello to all users and wizards.

I am regulary using 'boxplot' function or its analogue -
'bwplot' from
the 'lattice' library. But they are, as far as I understand, totally
flawed in functionality: they miss ability to select what they would
draw 'in the middle' - median, mean. What the box means - standard
error, 90% or something else. What the whiskers mean - 100%, 99% or
something else.
Is there any way to realize it? Or is there any other good data
visualization function for comparing means of various data groups?
Ideally I would like to have a bit more customised function for doing
that. For example, 'boxplot(a~b,data=d,mid='mean').
