GrowthData2 {FSA} | 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
