bioIndex: Calculate length based indices

In fishvice/husky: a collection of husky functions

Description

Calculates abundance and biomass survey indices based on length classes for a particular species in a given year.

Not really a husky function - but a script turned into a function

Usage

bioIndex(lengths, stations, sex, lenClass, yr, lwcoeff, ...)

Arguments

lengths	data.frame containing length measurement for a given species in a given survey year.
stations	data.frame containg station survey station informations.
sex	boolean A flag indicating if indices should also be compiled by sex
lenClass	numerical vector containing length classes to compile the indices for
yr	numerical value for year
lwcoeff	numerical vector of length 2, containing parameter a and b of the length weight relationship.
...	Other parameters to pass to Calc.index
