Hello. I am sorry for posting a (seemingly) simple question, but I have just spent 2 hours trying to find the answer, without success. I want to make a histogram with conditioning on a factor, using Trellis graphics. However, I do not want any colours (only black and white) either in the histograms or in the strip. There must be some simple argument but I can’t find it. Here is my code so far:> histogram(~GRC.SLA|as.factor(species.type),data=group.means,+ strip=function(...) + strip.default(...,style=1,factor.levels=c("Conifers","Trees","Herbs","Mo nocots"))) As a default, this produces the bars in a pale blue and the strip in orange-yellow. Thanks.

Does this help?
mydata <- data.frame(OPTIMISM =
c(29,35,26,22,30,37,29,32,25,35,38,33,41,28,40),
PARENTS = rep(c("Both Deceased", "One
Deceased",
"Both Alive"), c(4,5,6)))
library(lattice)
trellis.device(width=7, height=5, new = FALSE, col = FALSE, bg =
"white")
histogram(~ OPTIMISM | PARENTS, data=mydata)

Dear bill, Try opening the Trellis graphics device with trellis.device(color=FALSE).
