Hi, Without data or script... Regards, Pascal ----- Mail original ----- De?: Etienne RIFA <etienne.rifa at gmail.com> ??: r-help at r-project.org Cc?: Envoy? le : Mercredi 18 avril 2012 16h32 Objet?: [R] polar.plot "add" argument Hello I try to create a polar.plot in order to represent some paths. I have one more information: the signal quality. I created classes and I used the argument "add" to superimpose my different signal levels. the result: http://i180.photobucket.com/albums/x82/zetiem/21.png Normally, the hotter spots should follow the green path. Despite this, we can see that the shape of the paths are the same for hot spots but on a smaller scale. I think that polar.plot with "add" argument ignores the scale of the active plot. I saw that by changing the radius scale (elevation angle). With 0? at the center, I have the same polar.plot. But I don't know how to fix it. Have you any ideas? Thank you Etienne ???

Have you any ideas? >Hi Etienne, Without your data I can only guess at what might be going wrong. One guess is that you specified explicit values for the radial.lim argument in the initial call and then did not do so in the "add" call. If you don't want to send your data, try to create a fake data set that will do the same thing. Then I could try to debug it. Jim
