Description

Computes and displays the enhanced unified distance matrix for a feature of the training data.

Usage

map.feature(map, feature, explicit = FALSE, smoothing = 2)

Arguments

map

an object of type 'map'.

feature

an integer as the index of the feature.

explicit

controls the shape of the connected components.

smoothing

controls the smoothing level of the umat (NULL, 0, >0).

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 umat for the first feature of the map
map.feature(m, 1)
