Re-compute standardized survey indices for an alternative grid from a previous fitted "surveyIdx" model.

Re-compute standardized survey indices for an alternative grid from a previous fitted "surveyIdx" model.

Usage

redo_surveyidx(
  x,
  model,
  predD = NULL,
  myids,
  nBoot = 1000,
  predfix = list(),
  mc.cores = 1
)

Arguments

x

DATRASraw dataset

model

object of class "surveyIdx" as created by "get_surveyidx"

predD

optional DATRASraw object, defaults to NULL. If not null this is used as grid.

myids

haul.ids for grid

nBoot

number of bootstrap samples used for calculating index confidence intervals

predfix

optional named list of extra variables (besides Gear, HaulDur, Ship, and TimeShotHour), that should be fixed during prediction step (standardized)

mc.cores

mc.cores number of cores for parallel processing

Value

An object of class "surveyIdx"
