init_list: Initialize a list of random landscape objects

In cascade-wp6/socialecological: The economics of catastrophic shifts in arid rangelands.

Description

Initialize a list of random landscape objects

Usage

init_list(n, cover = NULL, width = 200, height = width,
  runif_range = c(0, 1))

Arguments

n	An integer number. Number of landscape objects to generate.
cover	A single numeric value. The average vegetation cover of the landscape. Defaults to NULL, which calls a random number generator drawing initial cover from within the range given in runif_range.
width	An integer number. The width of the lattice to generate. Defaults to 200.
height	An integer number. defaults to the same value as width to produce square landscape objects.
runif_range	A numeric vector of length two. Gives the lower and upper boundary of the random number generator for initial cover.

Value

A list of n landscape objects. The output object is of class "landscape_list", which can be processed by the functions list_update() and summary().

Examples

L0 <- init_list(100, runif_range = c(0.6,0.99), width = 25)
