| rpay-class {FLEDA} | R Documentation |
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.
"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}}{sum_a{C_{ay}}}
and
bar{P}_{a}=frac{sum_y{P_{ay}}}{Y}
P_{ay}^r=frac{P_{ay}}{bar{P}_{a}}
