Thanks Dieter for your help, but unfortunately your suggestion results
only in changing the color of the *lines* and not the color of the
*area* of the polygon.

I also tried to call "col" from within the panel.superpose

xyplot(est ~ x | cond, group = grp, data = data, type = 'b',
       upper = data$upper,
       lower = data$lower,
       panel = function(x, y, ...){
           panel.superpose(x, y, panel.groups = 'panel.bands',
col="gray", ...)###### here the change
           panel.xyplot(x, y, ...)
       })

still unsuccessfully.

Again, strangely enough, it accept the argument "border" but not the
argument "col".

Any other ideas ?

PS
Thanks also to Dennis Murphy for suggestions on ggplot2.
