plotting
Also going from memory Michael's ggplot should almost work but I think yo need to change symbol = id in the aes statement to geom_point(aes(shape = id)) although it may work in the first aes() statement. John Kane Kingston ON Canada

Hi alL,
I have a data frame with 4 columns: "value", "time", "group" and
"id".
I would like to plot "value" vs. "time" with different colors for
different levels of "group" and
different symbols for different values of "id".
I think I could do this but I would like to see what is an easier way
to
plot
the data this way.
Thank you vey much.
