In untb: Ecological Drift under the UNTB

Ecosystem diagnostics for output of untb()

Description

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

Usage

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.

plot(species.count(a),type="b")
matplot(species.table(a),type="l",lty=1)

jj <- a[2000,]
print(jj)
as.count(jj)
