Create a custom strip function which changes the names
of the factor levels. Here we have changed them from 1:2
to c("b", "a").
my.strip <- function(..., factor.levels) {
factor.levels <- c("b", "a")
strip.default(..., factor.levels = factor.levels)
}
x <- 1:10
y <- x*x
z <- gl(2, 5)
xyplot(y ~ x | z, strip = my.strip)
