dataWiFinches


West Indian Finches data
This data frame is a binary presence-absence matrix for West Indies finches (Fringillidae). Each row is a different species of finch and each column is one of the 19 major islands in the West Indies. Entries indicate the presence (1) or absence (0) of a species on an island. Data from Gotelli and Abele (1982).

Given a site by species interaction matrix, users can make inferences about species interactions by performance hypothesis comparing test statistics against a null distribution. The current package provides algorithms and metrics for niche-overlap, body size ratios and species co-occurrence. Users can also integrate their own algorithms and metrics within these frameworks or completely novel null models. Detailed explanations about the underlying assumptions of null model analysis in ecology can be found at http://ecosimr.org.
