Hello, Thanks for your answer. Of course I read the help but I didn't understand how to retrieve data from radial.lim. Maybe it is trivial for you but not for me.
Attached to this message you will find some test data but you will need to cast them using reshape and this line (assuming you import the test data as "data"): data2 <- cast(data, gid ~ azimut, value = "angle") Regards, Hugues. -----Message d'origine----- De : Duncan Murdoch [mailto:[email protected]] Envoyé : lundi 18 août 2014 16:45 À : Hugues François; [email protected] Objet : Re: [R] About radial.labels in plotrix On 18/08/2014 9:35 AM, Hugues François wrote: > Hello, > > > > As you can read in the small code below, I do not represent directly my data > but its inverse in the limits of my radial plot and I would like to reorder > grid labelling from the upper value at the center and the lower one at the > graph's border.

You didn't post any data to demonstrate with, but I would assume it's a character vector (or numeric that will be coerced to character) of the same length as radial.lim. Duncan Murdoch
