map.starburst: Generate Starburst For Map

In lutzhamel/popsom2: Functions for Constructing and Evaluating Self-Organizing Maps

Description

Computes and displays the starburst representation of clusters on a map.

Usage

map.starburst(map, explicit = FALSE, smoothing = 2, merge.clusters=TRUE, merge.range=.25)

Arguments

map	an object of type 'map'.
explicit	controls the shape of the connected components.
smoothing	controls the smoothing level of the map display (NULL, 0, >0).
merge.clusters	is a switch that controls if the starburst clusters are merged together
merge.range	is a range that is used as a percentage of a certain distance in the code to determine whether components are closer to their centroids or centroids closer to each other.

Examples

data(iris)

## set data frame and labels
df <- subset(iris,select=-Species)
labels <- subset(iris,select=Species)

## build a map
m <- map.build(df, labels, xdim=15, ydim=10, train=1000)

## display the starburst for the map
map.starburst(m)
