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
