interactiveClustering {ProjectionBasedClustering}

GUI for interactive cluster analysis

Description

This tool is an interactive shiny tool that visualizes a given generalized Umatrix and allows the user to select areas and mark them as clusters to improve a projection based clustering.

Arguments

Umatrix

[1:Lines,1:Columns] Matrix of Umatrix Heights

Bestmaches

[1:n,1:2] Array with positions of Bestmatches

Cls

[1:n] Classification of the Bestmatches

Details

Clicking on "Quit" returns the Cls vector to the workspace.

Value

List of

EnlargedUmatrix

[1:Lines,1:Columns] Matrix of Umatrix Heights taken four times and arranged in a square 2x2.

EnlargedBestmaches

[1:n,1:2] Array with positions of Bestmatches according to the enlarged umatrix.

EnlargedCls

[1:n] Classification of the Bestmatches according to the enlarged umatrix.

Umatrix

[1:Lines,1:Columns] Matrix of Umatrix Heights

Bestmaches

[1:n,1:2] Array with positions of Bestmatches

Cls

TopView_TopographicMap

Plot of a topographic map.

Note

If you want to verifiy your clustering result externally, you can use Heatmap or SilhouettePlot of the CRAN package DataVisualizations.
