R> library("streamMOA")
# 3 clusters with 5% noise
R> stream <- DSD_Gaussians(k=3, d=2, noise=.05)
 
# cluster with CluStream  
R> clustream <- DSC_CluStream(m=50, k=3)
R> update(clustream, stream, 500)
R> clustream
CluStream + k-Means (weighted)
Class: DSC_TwoStage, DSC_Macro, DSC 
Number of micro-clusters: 50 
Number of macro-clusters: 3
