CNull: Fast Algorithms for Frequency-Preserving Null Models in Ecology |
individual.based.communities.a |
Produces a set of random communities from a given matrix, based on the individual-based null model (Stegen et al. 2013). These communities can be used for alpha diversity computations |
individual.based.communities.b |
Produces random pairs of communities from a given matrix, based on the individual-based null model (Stegen et al. 2013). These communities can be used for beta diversity computations |
