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

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

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))
