[R-sig-eco] Doubt about function colext() of package Unmarked. Wrong estimates for a metapopulation simulation.

2012-11-24 Thread Augusto Ribas
Hello dear list. I was using function colext to estimate colonization and extinction of simulated data and i'm not getting what i expected. Hope someone can enlighten me here. The way i'm simulating is the one used in the The R Book (M Crawley), chapter 26. But its pretty straight forward. You mak

The problem seems to be the way you are generating the 0's and 1's and not colext in unmarked. One can obtain a rough estimate the colonization and extinction probabilities from any two neighboring pairs of seasons (although in practice you'd want to use all of the data). Take seasons 29 and 3

[R-sig-eco] post-hoc test for adonis PERMANOVA

2012-11-24 Thread Andre Rovai
Dear friends, I have been recently introduced to R and am dedicating myself to go deeper on it. It can be tricky sometimes for a rookie, though! I ran a PERMANOVA (vegan package) using the adonis() function and tried to go deeper in the analysis by running a post-hoc test (betadisper()). I do app
