You want factor.level, not var.name in strip.custom.
Here's an example with the iris data. Apologies for the second line;
there's almost certainly an easier way to do it, but you (hopefully) get
the idea.
flevels <- levels(iris$Species)
foo <- paste("c(", paste("expression(paste(", flevels, ", sqrt(", 1:3,
")))", sep="", collapse=","), ")")
xyplot(Sepal.Length ~ Petal.Length | Species,
data = iris,
strip=strip.custom(factor.levels=eval(parse(text=foo
