I think this is want you want but without an example I am not certain
dat = expand.grid(t1 = gl(3,4), t2 = gl(5,4))
dat$y = rnorm(240)
dat$x = 1:12
xyplot(y~x|t2*t1,dat, as.table = T)
my.strip <-
function(which.given, ..., factor.levels) {
levs <- if (which.given == 2) c("Concord","HAL","Pierce") #levels
for second factor T2
else paste("T2 ", 1:5) #levels for first factor
strip.default(which.given, ..., factor.levels = levs)
}
xyplot(y~x|t2*t1,dat,
as.table = T,
par.settings = list(add.text = list(cex = 0.7)),
strip = my.strip,
layout = c(5,3))
The par.settings is a cheats way of changing the cex
# Change order
my.strip2 <-
function(which.given, ..., factor.levels) {
levs <- if (which.given == 2) c("HAL","Concord","Pierce") #levels
for second factor T2
else paste("T2 ", 1:5) #levels for first factor
strip.default(which.given, ..., factor.levels = levs)
}
xyplot(y~x|t2*factor(dat$t1, levels = c(2,1,3)),dat,
as.table = T,
par.settings = list(add.text = list(cex = 0.7)),
strip = my.strip2,
layout = c(5,3))
or can reorder

Hi
I attach the data and a xyplot I made using strip.default;
# This is my code;
trellis.device(col=F)
xyplot(GrainM~Nrate|S*Loc, data = Ahmed,
layout=c(5,3,1),
xlab=expression(bold(paste("N rate (kg ", ha^-1,")"))),
#xlab=expression(paste("Herbicide rate (g isoxaflutole ", ha^-1, ")")),
#ylab=expression(paste("Root dry weight (mg ", pot^-1,")")),
ylab=expression(bold(paste("Grain yield (Mg ",ha^-1,")"))),
ylim=c(10,20), #xlim=c(-50,700),
strip = function(...) strip.default(...,style = 1), col=0,
par.strip.text = list(cex = 0.7),
scales =
list(alternating=F,y=list(at=c(10,12,14,16,18,20,22)),font=2, cex=0.7,
col="black"),aspect = 1,
panel = function(x,y,subscripts,groups,...) {
#panel.grid(-1,-1)
m1 <- lm(y ~ x)
x.seq <- data.frame(x=seq(min(x)*0.95,max(x)*1.05,max(x)/10))
pred <- predict(m1, x.seq, se.fit=T)
grid.polygon(c(x.seq$x,rev(x.seq$x)),
c(pred$fit + 2*pred$se.fit, rev(pred$fit - 2*pred$se.fit) ),
gp=gpar(col=0, fill="light grey", alpha = 1), default.units
= "native")
llines(x.seq$x, pred$fit, lty = 1)
panel.xyplot(x,y)
print(round(summary(m1)$coef[ 2,c(1,4) ],3) )
ltext(50,18.4,paste("Slope = ",round(summary(m1)$coef[
2,c(1,4) ],3),sep=""),
cex=0.65, adj=0)
ltext(50,19.5,paste("Intercept = ",round(summary(m1)$coef[
1,c(1,4) ],3),sep=""),
cex=0.65, adj=0)
print(summary(m1))
}
)
## I want to force the model to write the names of locations as
"Concord","HAL","Pierce" from top to bottom instead of Loc.
Thanks for your help.
