fdata: A Sample Species Abundance Dataset

Description Value Author(s) Examples


A simple hypothetical data set used in many of the examples.


There are 3 datasets, however 2 of them (fdata.mat and fdata.lats) derive from the first (fdata.list). fdata.list is a table with 5 columns descriing the sample site, species name, abundance, and location in latitude/longitude. fdata.mat is a 12 by 12 species abundance matrix (12 unique species and 12 unique samples/localities) that can be recreated from the original table of occurrences using the create.matrix() function; likewise, the fdata.lats() contains the locations of each of the samples, and can be created using the create.lats()
