plot.World: Plots information about world object

Description

Plot assumes that the World object contains only Niches objects. See arguments for details.

Usage

# S3 method for World
plot(x,
	type=c("chromosomes", "fitness"),
	horiz=TRUE,
	pch=19,
	col=1,
	main="",
	xlab="",
	ylab="",
	chromosome=NULL,
	chromosome.chr="U",
	...)

Arguments

type

The type of plot. "chromosomes" will plot the chromosomes in one axis and the genes in the other axis. The maximum chromosome is drawn with "M", the best chromosome with "B" and the user chromosome with "U". This plot give an overview of the population coverage. "fitness" plot the current fitness in vertical axis against chromosome index in horizontal.

horiz

Exchange the default choice of axis when type="chromosomes".

main,xlab, ylab,col,pch

World defaults for common plot parameters. Their usage overwrite the default value. col controls the color for chromosomes

chromosome

An additional chromosome for comparison.

chromosome.chr

Explicit character for additional chromosome.

chromosomes

Use the specific list of chromosomes instead of the original Niche chromosomes.

...

Other user named values to include in the object.

Value

Returns nothing.

Examples

Run this code

# NOT RUN {
   cr <- Chromosome(genes=newCollection(Gene(shape1=1, shape2=100),5))
   ni <- Niche(chromosomes=newRandomCollection(cr, 10))
   ni$fitness <- runif(10)  ## tricky fitness
   ni
   wo <- World(niches=newRandomCollection(ni,2))
   refreshStats(wo)
   plot(wo, main="My Niche")
   plot(wo, type="fitness")
 
# }
