For the record, the problem with the old lattice (0.18) was that
panel.superpose() didn't pass on 'col' to panel.groups; it passed on
'col.line' and 'col.symbol' instead. (Actually, it passed on col=NA,
which is even worse). This was OK for the default
panel.groups=panel.xyplot, but obviously a problem in cases like this.
lattice 0.19 fixes this.
One approach that will work both versions is to use a different
parameter that panel.superpose() does pass on. 'fill' seems
appropriate here, e.g.,
panel.bands <-
function(x, y, upper, lower,
subscripts, ..., col, fill)
{
upper <- upper[subscripts]
lower <- lower[subscripts]
panel.polygon(c(x, rev(x)), c(upper, rev(lower)), ..., col = fill)
}
xyplot(est ~ x | cond, group = grp, data = data, type = 'b',
upper = data$upper,
lower = data$lower,
fill = "grey",
panel = function(x, y, ...){
panel.superpose(x, y, panel.groups = 'panel.bands', ...)
panel.xyplot(x, y, ...)
})
