flexclust (version 1.1-0)

conversion: Convert S3 Partition Objects to KCCA

Description

These functions can be used to convert the results from cluster functions like kmeans or pam to objects of class "kcca".

Usage

as.kcca(object, ...)
## S3 method for class 'kmeans':
as.kcca(object, data, save.data=FALSE, ...)
## S3 method for class 'partition':
as.kcca(object, data=NULL, save.data=FALSE, ...)

Arguments

object

fitted object.

data

data which were used to obtain the clustering. For "partition" objects created by functions from package cluster this is optional, if object contains the data.

save.data

Save a copy of the data in the return object?

...

currently not used.

Examples

data(Nclus)

cl1 = kmeans(Nclus, 4)
cl1
cl1a = as.kcca(cl1, Nclus)
cl1a

<testonly>stopifnot(all.equal(cl1$cluster, clusters(cl1a)))</testonly>

library("cluster")
cl2 = pam(Nclus, 4)
cl2
cl2a = as.kcca(cl2)
cl2a
## the same
cl2b = as.kcca(cl2, Nclus)
cl2b

<testonly>stopifnot(all.equal(clusters(cl2a), clusters(cl2b)))
stopifnot(all.equal(parameters(cl2a), parameters(cl2b)))</testonly>
