Hi all,
I am running species accumulation curves for several data-sets, and am also
playing with some estimators with this function in vegan:
SF.estimators-poolaccum(SF.data,permutations=1000)
SF.estimators # shows data for Sobs, Chao, both Jacks and bootstrap
plot(SF.estimators) # illustrates
Dear list,
I am kind of new to R. I want to fit the nonlinear Morgan-Mercer-Flodin (MMF)
growth model in a species accumulation curve (SAC) run with vegan package in
.R. I would very much appreciate if you could give some feedback. My first
question is what's the best approach i) grofit
Dear list,
I am comparing species accumulation curves (in marine fouling communities) from
12 different ecoregions and I could use some help. One way to do this is to
compare the asymptote's location (when fiting a non-linear curve). This is
done. However I came across with this Davies test
:
LTR.LME - lme(LTR~RTR+RFR+OS+LFR+month, random=~1|region/plate)
regards
Mike

Hi all,
First of all thanks to all for helping me with my previous post on negative
binomial.
As I mentioned I got a paper back for revision requesting alternative analysis,
and I am seeking advice from the forum. I really appreciate any help you could
provide.
My major question was to
Hi all,
1st time user here!
I am an ecologist working with marine fouling assemblages. I just got a paper
back for revision. I am working with count data (species richness). I have used
a linear model but the reviewers are recommending the use of negative binomial
or Poisson. As far as I could
