logisticMap: Logistic map

In nonlinearAnalysis: R package for nonlinear time series analysis

Description

Generates a time series using the logistic map.

Usage

  logisticMap(r = 4,
    start = runif(n = 1, min = 0, max = 1),
    n.sample = 5000, n.transient = 500, do.plot = TRUE)

Arguments

start	A numeric value indicating the starting value for the time series. If the starting point is not specified, it is generated randomly.
r	The r parameter. Default: 4
n.sample	Length of the generated time series. Default: 5000 samples.
n.transient	Number of transient samples that will be discarded. Default: 500 samples.
do.plot	Logical value. If TRUE (default value), a plot of the generated logistic system is shown.

Details

The logistic map is defined as follows:

x[n] = r * x[n-1] * (1 - x[n-1])

The default selection for the r parameter is known to produce a deterministic chaotic time series.

Value

A vector containing the values of the time series that has been generated.

Note

Some initial values may lead to an unstable system that will tend to infinity.
