rpay-class: Class "rpay" for relative proportion at age per year
In FLEDA: Exploratory Data Analysis for FLR

Description Creating Objects from the Class Slots Extends Methods Details See Also Examples

This class encapsulates results of a rpay method.

Objects of this classe should be created with a call to the contructor function rpay(object, ...), where object must be an object of class "FLQuant" and ... can be used to pass trim arguments to the creator funtion.

rpay: Object of class "FLQuant".

Class "FLQuant", directly.

Inherits from "FLQuant".

Considering C_{ay}, the catch in numbers at age a=1,…,A per year y=1,…,Y, obtained e.g. from the catch.n slot of a "FLStock" object, the computation of rpay P_{ay}^r is:

Consider:

P_{ay}=\frac{C_{ay}}{∑_a{C_{ay}}}

and

\bar{P}_{a}=\frac{∑_y{P_{ay}}}{Y}

P_{ay}^r=\frac{P_{ay}}{\bar{P}_{a}}
