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) xyplo

[R] formatting POSIXlt object as strip labels in lattice plot

2007-11-22 Thread John Field
