Odp: Problem with segmented function
Hi
Hi, I appreciate your help with the segmented function. I am relatively new
to
R. I followed the introduction of the 'segmented'-package by Vito
Muggeo,
but still it does not work. Here are the lines I wrote: data_test<-data.frame(x=c(1:10),y=c(1,1,1,1,1,2,3,4,5,6)) lr_test<-lm(y~x,data_test) seg_test<-segmented(lr_test,seg.Z~x,psi=1)
You did not read help page correctly. seg.Z is named parameter in which you specify formula without LHS. psi shall be x near the expected slope change. seg_test<-segmented(lr_test,seg.Z=~x,psi=5) works corretly Regards Petr
/error in segmented.lm(lr_test, seg.Z ~ x, psi = 1) : A wrong number of terms in `seg.Z' or `psi'/ Thank you very much, Stella -- View this message in context:
