In lbozyk/IFSbmp: Plotting IFS type fractals

Description

Draws a plot for an object of class IFS with adjustable parameters of depth and starting point for IFS iterations.

Usage

## S3 method for class 'IFS'
plot(x = NULL, start = c(0, 0), depth = 1, ...)

Arguments

x	A list of class IFS.
start	Coordinates of the starting point for the IFS method.
depth	Parameter indicating number of iterations to be executed.
...	Additional parameters of the generic plot function.

Value

Plotted fractal image.

Examples

lin <- function(a,b,c,d,e,f){function(x,y) {c(a*x+b*y+c,d*x+e*y+f)}}
plot(createIFS(lin(.5,-.5,0,.5,.5,0),lin(-.5,-.5,1,.5,-.5,0)),depth=16,type="p",cex=.1,col="orange")

f <- lin(1/2,0,0,0,1/2,0); g <- lin(1/2,0,1/2,0,1/2,0); h <- lin(1/2,0,1/4,0,1/2,sqrt(3)/4)
plot(createIFS(f,g,h),depth=8,cex=.1)

lin3 <- function(a,b) {lin(1/3,0,a/3,0,1/3,b/3)}
plot(createIFS(lin3(0,0),lin3(0,1),lin3(0,2),lin3(1,0),lin3(1,2),lin3(2,0),lin3(2,1),lin3(2,2)))

plot(createIFS(lin(0,0,0,0,0.16,0),lin(0.85,0.04,0,-0.04,0.85,1.6),lin(0.2,-0.26,0,0.23,0.22,1.6),
lin(-0.15,0.28,0,0.26,0.24,0.44)),depth=9,type="p",cex=.5,col="green")
