growth_VB2: von Bertalanffy growth function (using L0)

In marchtaylor/fishdynr: Fisheries science related population dynamics models

Description

growth_VB2 describes the growth as a function of age (t) using the von Bertalanffy growth function. The function differs slightly from growth_VB by using L0 instead of t0 to describe the growth function origin

Usage

growth_VB2(Linf, K, t, L0)

Arguments

Linf	Infinite length
K	growth constant
t	age
L0	(hypothetical) length at time zero

Examples

t <- seq(0,5,0.1)
L <- growth_VB2(Linf=100, K=0.5, t=t, L0=10)
plot(t, L, t="l", ylim=c(0,110), xaxs="i", yaxs="i")
points(0,10); abline(h=100, lty=2, col=8)
