ReadData: Reading sequences of visited states

In ClickClust: Model-Based Clustering of Categorical Sequences

Description

Prepares sequences of visited states for running the EM algorithm.

Usage

click.read(S)

Arguments

S	list of numeric sequences

Details

Prepares sequences of visited states for running the EM algorithm by means of the click.EM() function.

Value

X	dataset array (p x p x n) (p - # of states, n - # of sequences)
y	vector of initial states (length n)
