Hi Thiery, Thanks for the corrected line. I did manage to plot it now, but instead of one unified legend now I have two separate legends - one for the 5 colors, Marked with "Tree" on the top and another for the 4 linetypes, marked with "Lines" at the top. any idea how to unify them?

Dear Tribo,
I've made a little mistake. It should have been
Orange2 <- data.frame(Tree = as.factor(Tree_v), age = age_v,
circumference = circumference_v)
Orange2$Lines <- factor(as.numeric(Orange2$Tree) %% 4)
Have a look at help("%%")
HTH,
Thierry

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.

Hi Thierry
Thanks for replying. I tried your code, but it spit an error on me:
> Orange2 <- data.frame(Tree = as.factor(Tree_v), age = age_v,
+ circumference = circumference_v, Lines = factor(as.numeric(Orange2$Tree) + %% 4)) Error: unexpected SPECIAL in: "Orange2 <- data.frame(Tree = as.factor(Tree_v), age = age_v, circumference = circumference_v, Lines = factor(as.numeric(Orange2$Tree) + %%" Am I typing it correctly? What does the %% 4 or %%5 mean by the way? Regards, TL On Wed, Mar 26, 2008 at 11:26 AM, ONKELINX, Thierry <Thierry.ONKELINX at inbo.be> wrote:
