Just one more thing: when you do find a solution, can you please share it with us?
I do trust nlraa::boot_nlme() as it's been deliberately written for nonlinear mixed-effects models, but the fact that intervals() is inherited from the 'lme' class without any mention of nonlinear models in the manual worries me. I don't know if it's intended to work with 'nlme' models. -- Best regards, Ivan ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
