R help - Dec 2007 - lattice: axes drawn when relation='free' or relation='sliced' but not when relation='same'

I'm using lattice to draw a multi-panel figure: 5 rows, 4 columns.  The
y-axis for each panel is determined by

  yaxs            <- list(draw=T
                          , labels=c(0, '.5', '1',
'1.5')
                          , at=c(0, .5, 1, 1.5)
                          , tck=c(.4, 0)
                          , cex=.7
                          , alternating=2
                          , relation='same'
                          , rot=90)

fig1 <- xyplot( [...], scales=list(x=xaxs, y=yaxs))

I want this to draw ticks and labels on the left-hand side of each panel. 
Instead, I get ticks on the left-hand side of only the
panels in the leftmost column, and labels only on the right-hand side of the
rightmost column.  What can account for that?

What seems especially peculiar is that when I change relation to
'sliced' or 'free', the axes are drawn as I want them to be
drawn.

The data that I'm plotting are numeric and range from -.3 to 1.9.  I'm
using R 2.6.1 and lattice 0.17-2 on Windows XP.

Thank you,

Account for what? What you have described is a fundamental aspect of
the design of Trellis graphics (which clearly happens to be different
from how you would have designed it, but so what?).

Well, doesn't seem very peculiar to me.

If you want the same limits in every panel even when relation="free",
put in an explicit ylim=c(-0.2, 2) or something similar.
