A function to find length-weight relationship parameters a and b

Description

A function to find estimates length-weight relationship parameters available on fishbase. It returns a list of means and standard deviations of a and b obtained from: *Froese, R., J. Thorson and R.B. Reyes Jr., 2013. A Bayesian approach for estimating length-weight relationships in fishes. J. Appl. Ichthyol. (2013):1-7.* Please cite Froese et al. (2013), when using these values. The default mirror for fishbase is set to "de", please change this if needed for your location

Usage

find_lw(sp, mirror = "us")

Arguments

sp	A charachter value containing the species name
mirror	Mirror for fishbase (eg. "de", "org", "us", etc.) Default is "us".

Value

A dataframe with means and standard deviations of length-weight parameters

Examples

library(fishflux)
library(plyr)
# find length-weight relationship parameters for one species
find_lw("Lutjanus griseus")

# find length-weight relationship parameters for multiple species and return in dataframe
ldply(lapply(c("Chlorurus spilurus","Zebrasoma scopas"), find_lw))
