Try this:
p <- bwplot(Error~Method | sigma + INU, data = z,
scales = list(rot=90), horiz = FALSE,
layout = c(5,3), col = "red")
require(latticeExtra)
useOuterStrips(p,
strip = <<your sigma-strip function>>,
strip.left = strip.custom(
var.name = "INU", sep = " = ",
strip.names = TRUE)
)
This works!! Thanks very much!! May I also ask how I can put in a "%"
after the INU value? i.e., I want the labels to be INU = 0%, INU = 20%,
INU = 40% (instead of INU = 0, INU = 20 and INU = 40).
Define:
INUExpr <- paste0("INU = ", c(0,20,40), "%")
Then
useOuterStrips(p,
strip = <<your sigma-strip function>>,
strip.left = << your strip function with
var.name = INUExpr[which.panel] >>
)

Thanks, Peter! I have been trying things like this all afternoon. But i
still get the same problem:
The following, from your earlier e-mail works (cut-and-paste should be
fine):
library(lattice)
library(latticeExtra)
z <- cbind(rep(c("BIC", "ICL", "s_v", "Q_v", "sig-q",
"s_lsk", "s_lML", "s_mlsk", "s_mlML", "s_la8",
"s_haar"), each = 250), rep(c(5, 10, 20, 30, 50), each = 50))
z <- rbind(cbind(z, 0), cbind(z, 20), cbind(z, 40))
z <- cbind(z, rnorm(n = nrow(z)))
z <- as.data.frame(z)
names(z) <- c("Method", "sigma", "INU", "Error")
sigma <- as.numeric(levels(z$sigma))
sigmaExprList <- lapply(sigma, function(s) bquote(italic(sigma) == .
(s))) sigmaExpr <- as.expression(sigmaExprList)
p <- bwplot(Error~factor(Method, levels = unique(Method)) | sigma +
INU, data = z, scales = list(rot=90), horiz = FALSE,
layout = c(3,5), col = "red")
require(latticeExtra)
useOuterStrips(p,
strip = function(which.given, which.panel, var.name,
strip.levels = FALSE,
strip.names = TRUE, ...) {
strip.default(which.given, which.panel,
var.name = sigmaExpr[which.panel],
strip.levels = FALSE,
strip.names = TRUE, ...)
},
strip.custom(
var.name = "INU", sep = " = ",
strip.names = TRUE))
However, this (edition of the latter) does not:
INUExpr <- paste0("INU = ", c(0,20,40), "%")
useOuterStrips(p,
strip = function(which.given, which.panel, var.name,
strip.levels = FALSE,
strip.names = TRUE, ...) {
strip.default(which.given, which.panel,
var.name = sigmaExpr[which.panel],
strip.levels = FALSE,
strip.names = TRUE, ...)
},
strip.left = function(which.given, which.panel, var.name,
strip.levels = FALSE,
strip.names = TRUE, ...) {
strip.custom(
var.name = INUExpr[which.panel],
strip.names = TRUE, ...)
}
)
Clearly, I am doing something wrong in defining the strip function. (It
does not help that i am not completely at home with it.) Can you or
someone please help some more?
Actually, it would work if you made strip.left a more accurate
copy of your strip function. But I hadn't taken a close enough
look at your strip function. I don't think it's needed at all.
Try this:
p <- bwplot(Error ~ Method | sigma + INU, data = z,
scales = list(rot=90), horiz = FALSE,
layout = c(5,3), col = "red")
useOuterStrips(p,
strip = strip.custom(
factor.levels = sigmaExpr),
strip.left = strip.custom(
factor.levels = INUExpr)
)
BTW, you don't need the italic() on sigma - it does nothing in plotmath.

Many thanks again!
