stream (version 1.0-3)

cluster: Cluster a Data Stream

Description

Clusters a number of input points from a data stream into a clustering object.

Usage

cluster(dsc, dsd, n = 1, verbose=FALSE, ...)

Arguments

dsc

a DSC object (clusterer).

dsd

a DSD object (data stream).

n

number of points to cluster.

verbose

report progress.

...

extra arguments for clusterer.

Value

• The updated DSC object is returned invisibly for reassignment (however, this is not necessary). To obtain the updated clustering result, call get_centers() on the DSC object.

Details

cluster takes n times a single data points out of the DSD and adds it to the clustering in the DSC object. Note that cluster directly modifies the DSC object (which is a reference class) and thus the result does not need to be reassigned to the DSC.

Examples

dsd <- DSD_Gaussians(k=3)
dsc <- DSC_DStream(gridsize=.05)  

cluster(dsc, dsd, 500)
plot(dsc, dsd)
