nay-class {FLEDA} | R Documentation |
This class encapsulates results of a nay
method.
Objects of this classe should be created with a call to the constructor function nay(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 nay
P_{ay} is:
P_{ay}=frac{C_{ay}}{max_a{C_{ay}}}
data(ple4sex) # compute catch proportions at age ple4sex.nay <- nay(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.nay, main=ttl, ylab=yttl, xlab=xttl, scales=ax)
