Description

Calculates the net reproductive rate of a stage classified matrix using the dominant eigenvalue of the matrix R

Usage

net.reproductive.rate(A, ...)

Arguments

A	projection matrix
...	additional items are passed to splitA and are used to split A into T and F matrices

Value

Net reproductive rate. If the transition matrix is singular, then NA is returned.
