Population Model Matrix Elements

Build population model matrix elements.

Usage

pop_model_matrix_elements(pop_mod_setup = NA)

Arguments

pop_mod_setup

List. Object returned from population_model_setup().

Value

a list object of symbolic objects.

Details

This is an intermediate setup function to run the population model. However, some of outputs are useful on their own, especially for eigen analyses. pop_model_matrix_elements() is run after pop_model_setup() or pop_model_setup_anadromous(), but pop_model_matrix_elements() must be run before Projection_DD(). Key outputs to explore include a density independent projection matrix, life histories, and a symbolic representation of the matrix math for density dependent and density independent components.

Examples

if (FALSE) { # \dontrun{

# Load the CEMPRA package.
library(CEMPRA)

filename_lc <- system.file("extdata", "life_cycles.csv", package = "CEMPRA")
life_cycles <- read.csv(filename_lc)

# Setup objects for population model
pop_mod_setup <- pop_model_setup(life_cycles = life_cycles)

# Build matrix elements for population model
pop_mod_mat <- pop_model_matrix_elements(pop_mod_setup = pop_mod_setup)
names(pop_mod_mat)

# A density independent projection matrix
pop_mod_mat$projection_matrix
