plot_ifsct {ctsfeatures}

Constructs the IFS circle transformation of a categorical time series

Description

plot_ifsct constructs the IFS circle transformation of a categorical time series.

Usage

plot_ifsct(series, alpha, beta, title = "IFS circle transformation", ...)

Arguments

series

An object of type tsibble (see R package tsibble), whose column named Value contains the values of the corresponding CTS. This column must be of class factor and its levels must be determined by the range of the CTS.

alpha

Parameter alpha in the circle transformation.

beta

Parameter beta in the circle transformation.

title

The title of the graph.

...

Additional parameters for the function.

Details

Constructs the IFS circle transformation for a given CTS, which is useful to identify cycles of arbitrary length.

Value

The IFS circle transformation.

ct <- plot_ifsct(sequence_1, alpha = 0.1, beta = 0.1) # Constructing the IFS circle transformation
