nlsList{nlme} control of min and max parameter bounds?
...on a selfStart function with a work-around loop in it. This subsetted the data by ID and performed separate nls fits with parameters constrained by the port algorithm. My objective was to use nlsList as an object for an nlme fit, so I was thinking of pasting together the details of the fits from my slefStart function into an object of class "nlsList" "lmList" but wasn't sure if this would work or was even appropriate.
