[R] superimposing xyplots on same scale

[Felix Andrews]

Um, no, please use doubleYScale() in latticeExtra, rather than as.layer().

However, in your case, why don't you just do a standard lattice plot like

xyplot(time_pct + pct_compl ~ date,
   par.settings = simpleTheme(col = c("blue", "red")),
   type="b",
   pch=15,
   ...)

If you gave a reproducible example I could give you a reproducible solution.

Cheers
