[R] What is the equivalent function in R to xyplot in S?

[bluesky315 at gmail.com]

Page 140 of MASS uses the function xyplot. But I don't find it in R.
Is there a package that I should load to use xyplot. Or there is a
function with a different name in R that does the same thing as xyplot
in S.

xyplot(Gas ~ Temp | Insul, whiteside, panel =
function(x, y, ...) {
panel.xyplot(x, y, ...)
panel.lmline(x, y, ...)
}, xlab = "Average external temperature (deg. C)",
ylab = "Gas consumption (1000 cubic feet)", aspect = "xy",
strip = function(...) strip.default(..., style = 1))
