simProd: Simulates productivity data

In IPMbook: Functions and Data for the Book 'Integrated Population Models'

Simulates productivity data

Description

Simulates a survey of breeding females, where a proportion of the females are included each year and the number of their offspring (male and female) recorded.

Usage

simProd(reprod, pInclude = 0.3, females.only = FALSE, verbose = TRUE)

Arguments

reprod	array with the reproductive performance of the population, usually the output from simPop.
pInclude	vector with the annual detection probabilities of broods; it can be scalar, used for all years.
females.only	if TRUE only the number of females that are produced is recorded. Default: total reproduction is recorded.
verbose	if TRUE, information is displayed in the console.

Value

A list with the following 2 components:

prod.ind	matrix with the individual reproductive output. The three columns give the output, the year of the brood and the actual age of the mother.
prod.agg	matrix with the same data, but aggregated. The two columns give the year-specific total number of newborn and the year-specific number of surveyed broods.
