phasePlots: Calculate Phase Plots

Description

Calculate phase plots

Usage

phasePlots(data, max.lag=1,diff=FALSE)

Arguments

data

A matrix, time series matrix, or an object of class TSdata.

max.lag

The maximum number of shifts to plot

diff

If TRUE the data is plotted against the difference with lagged values.

Value

None

Side Effects

A plot of (the phase space) the data against (differenced) lagged values is produced.

Details

Non-linearities may show up as a non-linear surface, but this is a projection so, for example, a spherical space would not show up. Some sort of cross-section window would show this but require even more plots. A good statistical test would be better!

Examples

# NOT RUN {
data("egJofF.1dec93.data", package="dse")
phasePlots(egJofF.1dec93.data)
# }
