R help - Oct 2007 - Lattice: par.ylab.text alpha ?

Hi all,
I've got R for windows 2.3.1
I'm trying to modify my lattice histograms.
The following does reset the y-label to blue, but I cannot turn off the label
(alpha=0), nor shift label position (I'm assuming that is what lineheight is
for).  Is 'lineheight' the equivalent of 'line' in mtext?
Am I erring somehow?
Thanks!

trellis.par.set(list(par.ylab.text=list(col='blue')))  #<- works
trellis.par.set(list(par.ylab.text=list(alpha=0)))  #<-no change, i.e. label
still there
trellis.par.set(list(par.ylab.text=list(lineheight=3)))  #<- label not moved

I assume I'm interpreting alpha correctly as this gets rid of axes:
trellis.par.set(list(axis.line=list(alpha=0)))

AFAIK, lineheight only applies to multiline labels (it gets forwarded
to grid). It does have an effect for such labels.

The alpha thing is a bug, specifically, a bug in
lattice:::getLabelList, which forgets to look at alpha. For your use,
a temporary fix is to use col="transparent".
