GrowthData2: Hypothetical growth data for testing seasonal age models.
In fishR-Core-Team/FSA: Simple Fisheries Stock Assessment Methods
GrowthData2 R Documentation
Hypothetical growth data for testing seasonal age models.
Description
Hypothetical lengths at seasonal ages. These data are useful for testing growth related functions (e.g., findGrowthStarts) as they were generated from known growth functions (e.g., von Bertalanffy) with some random error and are, thus, “as good as it gets” for testing.
Format
A data frame of 126 observations on the following 2 variables:
- age
Ages with decimals representing a fraction of a year
- tlS
Total length simulated from a the “Somers” parameterization of the von Bertalanffy growth function with Linf=450, K=0.3, t0=-0.5, C=0.9, and ts=0.1
Topic(s)
