In kstierhoff/atm: Functions Used for the Analysis of Acoustic-Trawl Method (ATM) Survey Data

Estimate CPS length

Description

Calculate the estimated length of CPS species from a known weight measurement, using the mass-length relationship models presented in Palance et al. 2019.

Usage

estimate_length(scientificName, weightg, model.type = "GLM", season)

Arguments

scientificName	A vector containing the species' scientific name (Clupea pallasii, Engraulis mordax, Sardinops sagax, Scomber japonicus, or Trachurus symmetricus).
weightg	A vector containing specimen weight, in grams.
model.type	The model used to estimate weight, either OLS (Ordinary Least Squares) or GLM (Generalized Linear Model).
season	The season in which the specimen was collected, either spring or summer.

Value

Specimen total length (TL), in millimeters.

Examples

estimate_length("Sardinops sagax", 5, model.type = "GLM", "summer")
