qkdbscan-class {qkerntool}

Class "qkdbscan"

Description

The qkernel-DBSCAN class.

Objects of class "qkdbscan"

Objects can be created by calls of the form new("qkdbscan", ...). or by calling the qkdbscan function.

Slots

clust:

Object of class "vector" containing the cluster membership of the samples

eps:

Object of class "numeric" containing the reachability distance

MinPts:

Object of class "numeric" containing the reachability minimum number of points

isseed:

Object of class "logical" containing the logical vector indicating whether a point is a seed (not border, not noise)

Methods

clust

signature(object = "qkdbscan"): returns the cluster membership

kcall

signature(object = "qkdbscan"): returns the performed call

cndkernf

signature(object = "qkdbscan"): returns the used kernel function

eps

signature(object = "qkdbscan"): returns the reachability distance

MinPts

signature(object = "qkdbscan"): returns the reachability minimum number of points

predict

signature(object = "qkdbscan"): embeds new data

xmatrix

signature(object = "qkdbscan"): returns the used data matrix
