Note that lattice can do that by using custom strip functions:

library(ggplot) # data resides here
library(lattice)

my.strip <- function(which.given, which.panel, ...)

   if (which.given == 1 && which.panel[2] == 2)

      strip.default(which.given, which.panel, ...)

my.strip.left <- function(which.given, which.panel, ..., horizontal)

   if (which.given == 2 && which.panel[1] == 1)

      strip.default(which.given, which.panel, horizontal = FALSE, ...)

histogram(~ tip/total_bill | sex + smoker, tips, strip = my.strip,

     strip.left = my.strip.left, par.settings = list(add.text = list(cex = 0.7)))
