apcluster (version 1.0.2)

show-methods: Display APResult objects

Description

Display method for S4 class APResult

Usage

## S3 method for class 'APResult':
show(object)

Arguments

object

An APResult object created by affinity propagation clustering

Value

• show returns an invisible NULL

Details

show displays the most important information stored in object, namely number of data samples, number of iterations, input preference, final objective function values, exemplars, and clusters. For accessing more detailed information, it is necessary to directly the corresponding slots (see APResult).

Examples

## create two Gaussian clouds
cl1 <- cbind(rnorm(100,0.2,0.05),rnorm(100,0.8,0.06))
cl2 <- cbind(rnorm(50,0.7,0.08),rnorm(50,0.3,0.05))
x <- rbind(cl1,cl2)

## compute similarity matrix (negative squared Euclidean)
sim <- negDistMat(x, r=2)

## run affinity propagation
apres <- apcluster(sim)

## show details of clustering results
show(apres)
