accumulation curves
Hi,
I am trying to fit a logarithmic trendline to a scatterplot of a
species accumulation curve. I've tried abline, lines, curve and
scatter.smooth but none of these work.
Can anyone help please,

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 MMMeans, MMruns, Michaelis-Menten). Do you know any function for doing this? Thanks a lot...
