R Documentation

Generate a vector of recruitment abundance for the dynamic pool model.

Description

These function is used to generate recruitment abundances across multiple years using different random function.

Usage

genRecruits(
  method = c("fixed", "uniform", "normal", "StrYC_Nth", "StrYC_randInt"),
  simyears = 50,
  Nrec = NULL,
  MinR = NULL,
  MaxR = NULL,
  meanR = NULL,
  sdR = NULL,
  Nthyr = NULL,
  sizeStr = NULL,
  avgFreq = NULL
)

Arguments

`method`	A single string to call the method of generating a vector of recruits. `fixed` generate recruitment based on a fixed value for each year of simyears, `uniform` generates recruitment based on random values from a unifrom distribution for each year of simyears, `normal` generates recruitment based on random values from a unifrom distribution for each year of simyears, `StrYC_Nth` generates recruitment based on a strong year class every Nth year, and `StrYC_randInt` generates recruitment based on a strong year classes at random intervals.
`simyears`	A single numeric that sets the number of years to simulate recruitment
`Nrec`	A single numeric that sets the fixed number of recruitment
`MinR`	A single numeric that sets the minimum recruitment abundance during simulations.
`MaxR`	A single numeric that sets the maximum recruitment abundance during simulations.
`meanR`	A single numeric that sets the mean recruitment abundance.
`sdR`	A single numeric that sets the standard deviation of recruitment abundance
`Nthyr`	A single numeric that sets the Nth year that a strong year class will occur
`sizeStr`	A single numeric that sets the multiplier for the strong year class relative to meanR
`avgFreq`	A single numeric that sets the average frequency of a strong year class.
