Sorry, doubleYScale is not appropriate, since you specifically want a
common y scale.
I think Baptiste was suggesting to use layer(), rather than
as.layer(): something like
xyplot(pct_compl ~ date, col="red", ...) +
layer(panel.xyplot(date, time_pct, col = "blue"))
But again, I would definitely recommend you do this with the standard
lattice interface in xyplot: use the 'groups' argument, or
(equivalently) specify two series in the formula.
