WebMay 9, 2024 · A logistic growth model can be implemented in R using the nls function. “nls” stands for non-linear least squares. The logistic growth function can be written as. y <-phi1/ (1+exp (- (phi2+phi3*x))) y = Wilson’s mass, or could be a population, or any response variable exhibiting logistic growth.
