[R] Estimate the average abundance using Poisson regression with a log link.

There is a no homework rule, but:

1. "abundance" + "poisson" seems to be an animal species abundance problem
in a capture-recapture framework.
2. If so, check out packages 'Rcapture' and 'SPECIES'. They both implement
several estimators, such as Burnham and Overton's jacknife or Chao's
estimators. (The poisson model is a natural one).
3. Personally, I prefer the first, but this is because I'm more used to it
and have never worked with 'SPECIES', just took a look at it.
