[R] turn off selected axes in bwplot

[William Briggs]

I want to turn off selected axes in bwplot.  I would like to only have the bottom axis drawn, with the others off.

I have a series of bwplots that I want on one device, like this:

p1<-bwplot(x1,box.ratio=.1)
p2<-bwplot(x2,box.ratio=.1)
...
print(p1,position=c(0,.8,1,1),more=T)
print(p2,position=c(0,.6,1,.8),more=T)
...

I know about the panel functions panel.bwplot() and panel.axis(), but I don't know how to directly call them and change, for example, the side parameter of panel.axis(), leaving all the other parameters of both panel functions untouched.  

The axis can be turned off altogether with:

trellis.par.set(axis.line = list( color="transparent"))

but this is obviously not what I need.
