When I enter your line:
df <- expand.grid(site=c("een","twee","drie","vier","vijf"),
????????????????? month=factor(3:12,levels=1:12,
?????????????????????????????? labels=month.abb, ordered=TRUE))
I get + signs in front of month and label, as expected, and it follows with <
When I convert that to use my own variable names to this:
df <- expand.grid(site=c("CrCr","NFSC","MFSC","SFSC","LMO","MCE","MUE","MLE"),
? ? monames=factor(3:12, levels=1:12,
?? ? ? labels=AprToDec, ordered=TRUE))
I get + signs in front of monames and labels, again as expected, but then it gives me another + sign. And if I try to add another ), it keeps giving me + signs. What is happening here?

Ha David,
Thanks for your reply.
For your last question, you have to change month into an ordered factor
variable:
library(lattice)
df <- expand.grid(site=c("een","twee","drie","vier","vijf"),
????????????????? month=factor(3:12,levels=1:12,
?????????????????????????????? labels=month.abb, ordered=TRUE))
df$conc <- rnorm(dim(df)[1])
dotplot(month~conc|site,data=df)
HTH, Gerrit

That worked nicely;? thanks again.? Here?s what I used for our data:
library(lattice)
df <-
expand.grid(site=c("CrCr","NFSC","MFSC","SFSC","LMO","MCE","MUE","MLE","MoCe"),months=1:9)
dotplot(months~conc | site, data=df)
The result is attached.? Is there a way to replace the month numbers on
the y axes with the names Apr-Dec?
