In optistock: Determine Optimum Stocking Times Used in Fishery Enhancements
inv_vb R Documentation
The inverse von Bertalanffy function (iVBGF)
Description
This function calculates the inverse of the VBGF, or, time it takes to grow
to a particular length
Usage
inv_vb(len, linf, k, t0)
Arguments
len
Numeric. A length at which to determine how long it takes to grow
linf
The L∞
parameter of the VBGF
k
The k parameter of the VBGF
t0
The t0
Value
A numeric vector of how long it takes to grow to length len
Examples
time <- 365
len_at_age <- vbgf(time, 30, (0.2 / 365), -0.2)
inv_vb(len_at_age, 30, (0.2/365), -0.2)
