The Cluster package provides functions to generate
and manage cluster hierarchies for a set of structures.
The actual clustering is done with the external
programs jclust and
kclust.
|
|
|
|
new([parameters]) |
|
creates a new Cluster object. Clustering parameters may given as hash-style key=>value pair arguments
|
|
|
|
setPar(parameters) |
|
sets clustering parameters in hash-style key=>value format
|
| |
|
setFileList(filelist) |
|
resets the top level cluster from a list of files. This method needs to be called before clustering can be done.
|
| |
|
runCluster([cluster][,method]) |
|
runs the jclust clustering program for the set of files in the top level cluster or in cluster if given as argument.
|
| |
|
clusterHierarchy([level[,cluster]]) |
|
generates a cluster hierarchy beginning at the top level cluster or at a cluster given as argument by calling runCluster recursively. The level argument sets the maximum number of cluster levels that may be performed recursively
|
| |
|
top() |
|
returns the top level cluster
|
| |
|
readFile(file) |
|
reads cluster information from a file
|
| |
|
writeFile(file[,centflag,centoutname]) |
|
writes the current cluster hierarchy to a file. Centroids are generated if centflag is set. The name used in the file template may be given through centoutname.
|
| |
|
writeCentroids(centoutname) |
|
writes the current cluster hierarchy to a file. Centroids are generated if centflag is set. The name used in the file template may be given through centoutname.
|
| |
|
$list = allClusters() |
|
return a list of all clusters
|
| |
|
$list = clusterList(level) |
|
return all clusters found at the given level
|
| |
|
$list = fileList(level) |
|
returns the list of files at a given level.
