Hi, I got this error every time when I put upper and lower bound on my parameters in nls. I'm not quite sure what this error is about. I also wanted to find the content of nls_port_fit. But typing this directly into R doesn't seem to give any result out. I also tried to see the content of If anybody could shed some light I'd greatly appreciate. Thank you. rc

some functions are 'hidden' in the package namespace. you can use
getAnywhere("nls_port_fit")
to see the source code of such functions.
and
getFromNamespace
to execute such functions from the R prompt.

Well, one might suspect that there's something wrong with the way you're specifying 'start' and 'lower' and/or 'upper'. But you're so secretive about what you're actually doing that one can only speculate. At a minimum, you might indicate what version of R you're using. -Peter Ehlers
