survprob: Calculating survival probabilties given mortality in the...

In FLCore: Core package of FLR, fisheries modelling in R.

Description

For an FLBiol object with the mortality-at-quant this method calculates the associated survival probability-at-quant. This can be later used by the r() method. The calculation can be carried out either by year or by cohort.

Usage

survprob(object, ...)

Arguments

object	An object of type FLBiol.
...	Extra arguments accepted by each implementation.

Details

Calculates the survival probability-at-quant given the mortality information in an FLBiol object - survival probability from one year to the next is simply exp(-M) and the survival probaiblity to a given quant is merely the product along the quant dimension of the individual survival probabilities.

Value

An object of class FLQuant.
