est_recruits: Calculate recrutiment from previous years population

In AustralianAntarcticDivision/tagsim: Simple population model for tag-based simulations

Description

Function returns number of recruits given last year's population size carrying capacity K, natural survivorship S and resilience r. rk is the number of recruits per unit spawner when B = K. var controls whether the recruitment is stochastic (var = F is used when calculating recruitment parameters)

Usage

est_recruits(type, rec_pars, var)

Arguments

type	recruitment function either "constant", "logistic", "bevholt" (Beverton Holt) or "ricker". The "lognorm" method is independent of population size
rec_pars	list of recruitment parameters
var	is recruitment stochastic (default=FALSE)
