survprob {FLCore} | R Documentation

## Calculating survival probabilties given mortality in the FLBiol object

### 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-class`.
`...` | Extra arguments accepted by each implementation.

### Details

Calculates the survival probability-at-quant given the mortality information in an `FLBiol-class` 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-class`.
