| logr-class {FLEDA} | R Documentation |
This class encapsulates results of a log ratio at age per method.
Objects of this classe should be created with a call to the contructor function logr(object, ...), where object must be an object of class "FLQuant" and ... can be used to pass trim arguments to the creator funtion.
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 logr L_{ay} is:
L_{ay}=log{frac{C_{ay}}{C_{a+1,y+1}}}
require(FLEDA) data(ple4) myp <- logr(catch.n(ple4)) plot(myp) # now trimming years myp <- logr(catch.n(ple4), year=c(1990:2000)) plot(myp)
