ageSpecificRepro: Calculate age-specific reproduction from matrix population... In jonesor/Rage: Miscellaneous functions for COMADRE/COMPADRE matrix databases

Description

This function uses age-from-stage decomposition methods to calculate age-specific rates of reproduction from a stage-classified matrix population model. A detailed description of these methods can be found in section 5.3.2 of Caswell (2001).

Usage

 `1` ```ageSpecificRepro(matU, matR, startLife, N) ```

Arguments

 `matU` The survival component of a matrix population model (i.e. a square projection matrix reflecting survival-related transitions; e.g. progression, stasis, and retrogression) `matR` The reproductive component of a matrix population model (i.e. a square projection matrix reflecting transitions due to reproduction; either sexual, clonal, or both) `startLife` The index of the first stage at which the author considers the beginning of life. `N` Maximum age to which age-specific reproduction will be calculated.

Value

A vector containing age-specific rates of reproduction, from ages 0 through `N`.
