TP1: Calculate Time Represented by Cut Segment

In GaryTruong/whiskR: Stable Isotope Analysis for Whisker Samples

Description

TP1 allows you calculate how much time is represented by a section of sampled tissue. It uses the discrete step by step von Bertanlanffy equation solved for time

Usage

TP1(L, L.asym, LP1, k)

Arguments

L	numeric; length of the sample
L.asym	numeric; asymptotic length
LP1	numeric; length of the sample minus the cut sampled segment
k	numeric; growth coefficient, calculate using the function k

Value

The value returned is the number of days represented by the cut segment.

Author(s)

The function was written by Gary Truong with collaboration from Ben Walker and Anna Lewis from the University of New South Wales

Examples

TP1(L = 100, L.asym = 150, LP1 = 90, k = 0.0126)
