Ecosystem diagnostics for output of untb()

Provides ecosystem diagnostics of species count datasets (species counts and species tables), useful for the output of untb()

Keywords

species.count(x)
species.table(x)
Arguments
x

An integer matrix whose rows are integers representing the individuals' species

Details

These functions takes a matrix argument, which is interpreted as the output of untb(...,keep=TRUE).

Function species.count() returns the total number of species present in each row (ie at each timestep).

Function species.table() returns a matrix \(M\) where M[i,j] column of the matrix is the abundance of species \(j\) at time i.
