Hello everybody, This is probably a classic but I cannot find an answer to this on the mailing list (i.e. with a google search restricted to the mailing list archive). Setting: par(new=T) plot(x,y) works but plot(x,y,new=T) doesn't while it is said in plot's help that ... arguments are passed to par. What am I missing? JiHO --- http://jo.irisson.free.fr/
