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?

David

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,
I do not know.
It must be that your AprtoDec object  is different from month.abb.
Anyhow it should contain the labels for all twelve months!
If I copy your command in an interactive session I just get the message
that AprtoDec is not defined.

I understand that you type the commands interactively in an R session?
I usually prefer using an editor to write the program, and execute with a
 > source("dotplot.R",echo=TRUE)
command.
I like an editor with syntax highlighting and shows matching brackets.

I have attached my dotplot.R to this mail.

Thanks.  What editor do you use?  I'm working in a Mac, if that makes a difference.
