Class "dbs"
Description
This class pertains to results of the application of function
dbs
.
Objects from the Class
Objects can be created by calls of the form new("dbs", ...)
or as a
result from calling function dbs
.
Slots
call
:Object of class
"call"
reporting the matched call.x
:Object of class
"matrix"
representing the clustered data points.prior
:Object of class
"numeric"
being the prior probabilities of belonging to the groups.dbs
:Object of class
"numeric"
reporting the densitybased silhouette information of the clustered data.clusters
:Object of class
"numeric"
reporting the group labels of grouped data.noc
:Object of class
"numeric"
indicating the number of clusters.stage

is applied to an object ofpdfClusterclass
.
Methods
 plot
signature(x = "dbs", y = "missing")
:S4 method for plotting objects of
dbsclass
. Data are partitioned into the clusters, sorted in a decreasing order with respect to their dbs value and displayed on a bar graph. Seeplot,dbsmethod
for further details. show
signature(object = "dbs")
:S4 method for showing objects of
dbsclass
. The following elements are shown:
the dbs index computed at the observed data;

The cluster membership of each data point;

 summary
signature(object = "dbs")
:S4 method for summarizing objects of
dbsclass
. The following elements are shown:
a summary (minimum, 1st quartile, median, mean, 3rd quartile, maximum) of the dbs values for each cluster;

a summary (minimum, 1st quartile, median, mean, 3rd quartile, maximum) of the dbs values for all the observations.
