Hi,
I have a question about the lme function in R. My question is: After I got
the object from function lme, why the numIter value of the object is always
NULL? Following is my code:
jjww<-lme(y~x*zz,data=simul,random=~x|group,
control=lmeControl(returnObject=TRUE))
attributes(jjww)
jjww$numIter
the first 20 observation of data simul are:
> simul
y x
zz group

Is there any control option to show this jjww$numIter ? Why is it always
NULL? Did anyone ever get a non-NULL value of it? I am really confused by
this. Thank you for any help.
