How do you persuade lattice to draw tick marks on both the left and right
side of the y-axis, when relation="free" in the scales component?
#Ticks appear on both sides
histogram(~height|voice.part, data=singer)
##Ticks only on left
histogram(~height|voice.part, data=singer,
scales=list(y=list(relation="free")))
Providing tck as a vector of length 2 doesn't seem to work, neither does
setting alternating=3 (since the argument is ignored, and I don't really
want the labels on both sides - just the ticks).
I'm sure I'm missing something obvious.

controlling lattice plot ticks with relation="free"

I had an off list reply that was very helpful, suggesting the use of
panel.axis. For posterity, here's my own answer to my problem, using
yscale.component. It's not a particularly natural solution, and it
requires manually increasing the horizontal spacing between plots (with
the between agrument), but it works.
myyscale.component <- function(...)
{
ans <- yscale.components.default(...)
ans$right <- ans$left
ans$right$labels$labels <- NULL
ans
}
histogram(~height|voice.part, data=singer,
scales=list(y=list(relation="free")),
yscale.component=myyscale.component,
between=list(x=.5))
