FLCohort-class: Class FLCohort

In FLCore: Core package of FLR, fisheries modelling in R.

Description

This class represents cohorts in columns. It simply shifts the typical matrix representation where cohorts are found on the diagonals, into a matrix where cohorts are found in columns. It is very usefull for all analysis that want to make use of cohorts instead of years.

Slots

.Data

Internal S4 data representation. array.

units

The data units in some understandable metric. character

Extends

FLArray array

Constructor

The FLCohort(object) constructor method allows simple creation of new FLCatch with the methods described below.

signature(object=FLQuant) :

Creates a FLCohort object from a FLQuant object. It simply shifts the matrix so that cohorts instead of years are located in the columns (second dimensions) of the array.

signature(object=array) :

Creates a FLCohort object from an array.

signature(object=missing) :

Creates a empty FLCohort object.

Methods

[(base) :

Subset method

bubbles(FLCore) :

Bubbles plot.

signature(x=formula,data=FLCohort)

ccplot(FLCore) :

signature(object=missing)

FLCohort(FLCore) :

Creator method based on FLQuant objects.

signature(object=FLQuant)
