Hi: When the question is: 'Are there any functions in R for ?', package sos is a good place to start: library(sos) # install if necessary findFn('MMeans') Well actually, MMMeans and MMruns came up dry, but Michaelis-Menten is a commonly occurring model in the biosciences: findFn('Michaelis-

[R] parametric estimators for species richness in R

Dear everyone, I am doing some work about species richness estimation. Nonparametric estimation (such as Chao1, Jacknife1) can be done just using function "specpool()" and "estimateR()" in package "vegan". The problem is that I can not found any functions for parametric estimation (such as MMMe
