I have been thinking about contributing it, if R-core thinks it's worthwhile, but I haven't gotten around to incorporating it into a version of predict.nls yet. In the meantime, if you install the emdbook package and look at ?deltavar, you may be able to get that to work for you ... (if not, get back in touch & I'll try to help -- maybe this will be the impetus to develop that code a bit more). cheers Ben Bolker ______________________________________________ R-help@r-project.org mailing list 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.
