[R] Need help using lattice

[Parkhurst, David F.]

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

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.
