From stream v1.2-3
by Michael Hahsler
Translate Micro-cluster IDs to Macro-cluster IDs
Translates micro-cluster ids into macro-cluster ids for
a DSC_Macro object.
Usage
microToMacro(x, micro=NULL)Arguments
- x
- a
DSC_Macroobject that also contains information about micro-clusters. - micro
- A vector with micro-cluster ids. If
NULLthen the assignments for all micro-clusters in x are returned.
Value
-
A vector of the same length as
micro with the macro-cluster ids.

Examples
stream <- DSD_Gaussians(k=3, d=2, noise=0.05, p=c(.2,.4,.6))
# recluster a micro-clusters
micro <- DSC_DStream(gridsize=0.05)
update(micro, stream, 500)
macro <- DSC_Kmeans(k=3)
recluster(macro, micro)
# translate all micro-cluster ids
microToMacro(macro)
# plot some data points in gray
plot(stream, col="gray", cex=.5, xlim=c(0,1), ylim=c(0,1))
# add micro-clusters and use the macro-cluster ids as color and weights as size
points(get_centers(macro, type="micro"),
col=microToMacro(macro),
cex=get_weights(macro, type="micro", scale=c(.5,3)))
# add macro-cluster centers (size is weight)
points(get_centers(macro, type="macro"),
cex = get_weights(macro, type="macro", scale=c(2,5)),
pch=3,lwd=3, col=1:3)
