In symbolicDA: Analysis of Symbolic Data

Description

Dynamical clustering of symbolic data based on symbolic data table

Usage

SClust(table.Symbolic, cl, iter=100, variableSelection=NULL, objectSelection=NULL)

Arguments

table.Symbolic	symbolic data table
cl	number of clusters or vector with initial prototypes of clusters
iter	maximum number of iterations
variableSelection	vector of numbers of variables to use in clustering procedure or NULL for all variables
objectSelection	vector of numbers of objects to use in clustering procedure or NULL for all objects

Details

See file ../doc/SClust_details.pdf for further details

Value
