vB: vB calculates the predicted von Bertalanffy length at age

In haddonm/datalowSA: A Package to Faciliate Application of Data poor Stock Assessments

vB calculates the predicted von Bertalanffy length at age

Description

vB calculates length at age for the von Bertalanffy curve.

Usage

vB(par, ages)

Arguments

par	is a vector the first three cells of which are Linf, K, and t0 for the VB curve; the fourth parameter will be sigma, the standard deviation of the normal likelihoods used with the residuals
ages	is a vector of ages

Value

a vector of predicted lengths for the vector of ages in 'ages'

Examples

ages <- seq(0,20,1)
pars <- c(Linf=50,K=0.3,t0=-1.0,sigma=1.0) # Linf, K, t0, sigma
cbind(ages,vB(pars,ages))
