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.

a <- untb(start=rep(1,50), prob=0.01, gens=2000, keep=TRUE)

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

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