Johnny Svensson Attractors

Description

Functions to calculate the sequence of points given by the following dynamical system in order to draw the attractor of the system.

• x[n+1]=d*sin(a*x[n])-sin(b*y[n])
• y[n+1]=c*cos(a*x[n])+cos(b*y[n])

runSvenssonAttractor calculates the attractor. makeSvenssonAttractor makes a component that calculates and plots the Attractor.

Usage

makeSvenssonAttractor(type = "points", ...)

runSvenssonAttractor(
  a = 1.4,
  b = 1.56,
  c = 1.4,
  d = -6.56,
  inputx = 0,
  inputy = 0,
  x = NULL,
  y = NULL,
  runTime = 1e+05,
  sampleSize = NULL,
  reuseInput = FALSE
)

Arguments

type	The name(s) of the plotting function(s) used to plot the component. Defaults to "points". This can also include the names of classes linked to a plotting function.
...	parameters passed to the component and the component function runSvenssonAttractor. See "details" for more information.
a, b, c, d	The four parameters of the attractor from the above equations.
