[R] identify in lattice

Does identify work in lattice plots?  I tried this in R 1.4.1 (original
release) on my Win2000 machine with lattice 0.4-0 and grid 0.5-1.

     > xyplot(y ~ x,
     + panel=function(x, y, ...){
     + panel.xyplot(x, y, col=2, pch=20, ...)
     + panel.lmline(x, y, type = "l")
     + identify(x, y)
     + })

I get a change of cursor after the data points and the LS line are plotted
(but before the axes are), but when I start clicking on points, all I get
are beeps.   When I click the right mouse button I get a window with
stop/continue choices and choosing stop produces the axes on the plot and a
bunch of  warnings about no point being within 0.25 inches.

Am I doing anything wrong or identify is not implemented in lattice

Thanks in advance,
