gol: Start a Game of Life (with a few extra rules)

In ptarroso/gameR: A small useless package to play games in R with your data

Description

The John Conway's Game of Life has only two rules... That was not enough for gameR...

Usage

gol(map=NULL, grid=NULL, mean=NA, sd=NA)

Arguments

map	A raster map defining your world. This is a 'raster' object (see the raster package) that defines the area where the Game of Life will unfold. It can define a suitable area (land) with data and non-suitable (ocean) with NA. It can also have values that when combined with the mean and sd further details living areas based on a normal distribution. If NULL, a rectangular map is created, covering the extent (-180, 180, -90, 90) with 2 degrees of resolution.
grid	This is the grid with the living elements. It may be NULL and some elements are randomly placed in the map. It can be set to a raster object with the same proprieties as "map" but with only zeros and ones. Of course, the 1s define the living cells.
mean	If not NA, it is the mean value of a normal distribution that defines suitable values in relation to the 'map' data.
sd	If not NA, it is the standard deviation of a normal distribution that defines suitable values in relation to the 'map' data.

Details

John Conways's idea was to simplify the game rules to the lowest number possible but still provide some complexity of a living automata. He ingeniously reduced the rules to only two: - If the cell is alive, then it stays alive if it has either 2 or 3 live neighbors - If the cell is dead, then it springs to life only in the case that it has 3 live neighbors There is an implicit third rule that is all other cells remain dead or die in the following generation. But, of course, gameR needs more rules! So I made a few changes. First, the Game of Life happens in an infinite plane. Not anymore. It happens on a map! The two extra rules: - I have removed the infinite plane but gave them a world. So, at the edges of the world, where land and water meet, the cells can now live forever where they contemplate the infinity on an ocean. - Cells only live with certain environmental conditions, so they die if those conditions are not met.

Value

Does not return anything... or maybe some joy and fun.

Examples

	# Simplest possible
	gol()

	# Use a world DEM
	dem <- raster(system.file("data/dem.tif", package="gameR"))
	gol(dem, mean=500, sd=250)
