| pay-class {FLEDA} | R Documentation |
This class encapsulates results of a pay method.
Objects of this classe should be created with a call to the contructor function pay(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 pay P_{ay} is:
P_{ay}=frac{C_{ay}}{sum_a{C_{ay}}}
data(ple4sex)
# compute catch proportions at age
ple4sex.pay <- pay(ple4sex@catch.n)
# fine tune
ttl <- list(label="Catch proportion at age for Plaice in IV", cex=1)
yttl <- list(label="age", cex=0.8)
xttl <- list(cex=0.8)
ax <- list(cex=0.7)
# plot
bubbles(age~year|unit, ple4sex.pay, main=ttl,
