gnls warning message
...ng factor reduced below minimum in NLS step
In addition: Warning message:
$ operator is deprecated for atomic vectors, returning NULL in:
control$nlmStepMax
What is new for me is the warning message. It appears when I try to
specify different settings using the control statement.For example:
> hm02<-gnls(ht~a1*hd*(1-a2*exp(-a3*(dbh/dq2))),data=hdat,
+ start=c(a1=1.04,a2=1.38,a3=2.88),weights=varExp(),
+ control=c(minFactor=1/2048))
Any comment will be appreciate
Thanks
