simulateTrawl: Simulate trawl stations from superindividuals.

In Sea2Data/pelfoss: Simulate acosutic-trawl surveys and produce survey estimated using Rstox

Description

simulateTrawl Simulated trawl data from the superindividuals inside a radius nautical mile radius around each trawl station, where the probability of selecting an individual from the superindividual is proportional to its number of (identical) individuals.

drawTrawlStationInd Draws trawl station locations as log-distances (acoustic PSU locations), where the probability of a log-distance to be selected is a mixture of the NASC values and the uniform probability along the track. The mixture is given by the probfact argument.

Usage

simulateTrawl(
  superind,
  fishStation,
  seed = 0,
  radius = 10,
  nn = NULL,
  N = 100,
  lengthunit = 2,
  superindFilter = NULL,
  LcmMean = NULL
)

drawTrawlStationInd(NASC, nstations = 1, seed = 0, probfact = 0)

Arguments

superind	The superind data read from readNcVarsAndAttrs (used in readNorwecomBiomass and readNorwecomSuperind).
x	The input NetCDF4 file.
