Examples

## Not run: FLPKG()

Compute a retrospective hindcast cross-validation of AAP indices

Description

The output of aaphcxval consist of a list with two elements, named 'stocks' and 'indices'. The first is an object of class FLStocks, each a peel from the restrospective run. The second element is a list of FLIndices object. The first FLIndices object, named 'data', is a copy of the input 'indices' argument, with the additioned catch.n slot, if originally missing. The next element, named as the final year of the data set, contains the naive prediction of the input FLIndices, while the remaining elements are the result of a hindcast prediction of the relevant indices, those within the year range of as set ny nyears.

Usage

aaphcxval(stock, indices, control, nyears = 5, nsq = 3, pin = NULL)

Arguments

stock

Input FLStock object.

indices

Input FLIndices object.

nyears

Number if years for retrospective, defaults to 5.

nsq

Number of years for average biology and selectivity, defaults to 3.

pin

dsata.frame of parameter estimates to use as starting values.

Value

A list containing elements 'stocks', of class FLStocks, and 'indices', a list of FLIndices objects. See details for the structure of this list.

Examples

data(sol4)
sxval <- aaphcxval(sol4 + fit, indices, control=control(fit),
  pin=stdfile(fit))
plotXval(sxval$indices)
plot(window(sxval$stocks, start=2005),
  metrics=list(SSB=ssb, F=fbar, Recruits=rec))

Slots

SLOT

Neque porro quisquam est qui dolorem ipsum (SLOTCLASS).

Validity

VALIDITY

Neque porro quisquam est qui dolorem ipsum.

You can inspect the class validity function by using getValidity(getClassDef('FLCatch'))

Accessors

All slots in the class have accessor and replacement methods defined that allow retrieving and substituting individual slots.

The values passed for replacement need to be of the class of that slot. A numeric vector can also be used when replacing FLQuant slots, and the vector will be used to substitute the values in the slot, but not its other attributes.

Constructor

A construction method exists for this class that can take named arguments for any of its slots. All slots are then created to match the requirements of the class validity. If an unnamed FLQuant object is provided, this is used for sizing but not stored in any slot.

Methods

Methods exist for various calculations based on values stored in the class:
