Hi, I'm a new user of R I'm using grofit package to fit the grouth curve, but what I actually need is parameters: maximum slope (?) and the maximum cell growth (A). Can you please explain , how can I get them (for all curves)? Thees parameters are objects from gcFitModel, but i didn't managed to get them like output.
