iUmapIsland: iUmapIsland

In Umatrix: Visualization of Structures in High-Dimensional Data

iUmapIsland

Description

The toroid Umatrix is usually drawn 4 times, so that connected areas on borders can be seen as a whole. An island is a manual cutout of such a tiled visualization, that is selected such that all connected areas stay intact. This 'shiny' tool allows the user to do this manually.

Arguments

Umatrix	Matrix of Umatrix Heights
BestMatches	Array with positions of BestMatches
Cls	Classification of the BestMatches

Value

Boolean Matrix that represents the island within the tiled Umatrix
