Grab intrinsic growth rate (r) parameter from Fishbase and SeaLifebase

Description

Function to download intrinsic growth rate (r) parameter for specific species from Fishbase and SeaLifebase. The r growth parameter will serve as prior in the bayesian analysis in the surplus production model.

Usage

rGrabber(SciName)

Arguments

SciName

insert scientific name for the fish or aquatic biota

Value

The r value is ranging from 0 to 1, where high r value represents the r strategist species and known to have more resilient characteristics when facing with fishing pressures (Adams, 1980; Kawasaki, 1980, 1983).

This function requires rfishbase package installed and internet connection.
