survey_over_years: Initialize Population

In peterkuriyama/hlsimulator: Simulate Hook and Line Survey

Description

This function initializes the spatial distribution of the fish population

Usage

survey_over_years(numrow = 10, numcol = 10, nfish = 1000, distribute,
  seed = 300, nyears = 15, location_list, random_locations = FALSE,
  nlocs = 10, move_func, nhooks, ndrops, scope, ...)

Arguments

numrow	Number of rows in matrix
numcol	Number of columns in matrix
nfish	Number of fish to allocate among matrix
distribute	Specify fish distribution to be 'uniform', 'patchy', or 'area' specific
seed	Set seed if distribute == random, defaults to 300
maxfish	Maximum number of fish that can be sampled at a time
percent	percentage of area to sample. Only necessary if distribute == 'patchy'
area	Specify area to distribute fish, options are 'upperleft', 'upperright', 'lowerleft', 'lowerright', 'upperhalf', 'lowerhalf', 'righthalf', 'lefthalf' Only necessary if distribute == 'area'

Examples

Uniformly distribute fish
initialize_population(numrow = 10, numcol = 10, nfish = 1000, distribute = 'uniform')

Distribute fish in upper right quadrant only
initialize_population(numrow = 10, numcol = 10, nfish = 1000, distribute = 'area',
                            area = 'upperright')

Distribute fish in upper half
initialize_population(numrow = 10, numcol = 10, nfish = 1000, distribute = 'area',
                            area = 'upperhalf')

Patchily distribute fish
initialize_population(numrow = 10, numcol = 10, nfish = 100, distribute = 'patchy',
  percent = .2)
