# vbrecruit.f: Proportion of a cohort recruiting each year, plots, wrapper... In duplisea/vbrecruit: Calculate proportion of a cohort recruit each year based on VB growth

## Description

Using a Von Bertalanffy growth function and parameters you supply, this determines the proportion of a cohort's numbers and biomass that are at or above different size classes each year

## Usage

 `1` ```vbrecruit.f(birth.year, final.year, Linf, k, t0, cv, lengths.of.interest) ```

## Arguments

 `birth.year` four digit year of birth `final.year` four digit final year of the growth projection (birth year + average max age is a good) `Linf` VB maximum length (cm) `k` VB k `t0` VB t-zero `cv` coefficient of variation on length for an age `lengths.of.interest` (often the length at recruitment to the fishery or a valuable size

## Examples

 ```1 2 3 4``` ```cohort.props.f(birth.year=2011, final.year = 2030, Linf = 42, k = 0.086, t0 = -1.57, cv = 0.089) vb.growth.f(age.vector=1:40,Linf=42,k=0.086,t0=-1.57,cv=0.089) recruit=vbrecruit.f(birth.year=2011, final.year = 2035, Linf = 42, k = 0.086, t0 = -1.57, cv = 0.089, lengths.of.interest=c(25,22,27,30,35)) ```
