cohort.props.f: Proportion of a cohort recruiting each year

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

cohort.props.f(birth.year, final.year, Linf, k, t0, cv)

Arguments

birth.year	four digit year of birth
final.year	four digit final year of the growth projection (birth year + average max age is good)
Linf	VB maximum length (cm)
k	VB k
t0	VB t-zero
cv	coefficient of variation on length for an age

Examples

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=0.1)
