Llin.method: Fit size spectrum using Llin method

In andrew-edwards/sizeSpectra: Fitting Size Spectra to Ecological Data Using Maximum Likelihood

Fit size spectrum using Llin method

Description

Fit size spectrum using Llin method, which is plotting binned counts on log-linear axes and then fitting a linear regression.

Usage

Llin.method(bodyMass, num.bins = NULL, binBreaks = NULL)

Arguments

bodyMass	vector of individual body masses
num.bins	number of bins to be used, though this is only a suggestion since can get over-ridden by hist()
binBreaks	breaks for the bins to be used to bin the data and then fit the regression

Value

list containing:

• mids: midpoint of bins

• log.counts: log(counts) in each bin

• counts: counts in each bin

• lm: results of the linear regression of log.counts ~ mids

• slope: slope of the linear regression fit

• breaks: bin breaks

• confVals: 95\
