In Radviz: Project Multidimensional Data in 2D Space

Filtering out anchors with low contributions to the projection

Description

Filtering out anchors with low contributions to the projection

Usage

anchor.filter(x, lim = 0)

Arguments

x	a radviz object as produced by do.radviz
lim	the minimum length of an anchor

Details

When anchor.filter is a number and type is not Radviz, any springs whose length is lower than this number will be filtered out of the visualization. This has no effect on the projection itself.

Value

a radviz object as produced by do.radviz

Examples

data(iris)
das <- c('Sepal.Length','Sepal.Width','Petal.Length','Petal.Width')
S <- make.S(das)
rv <- do.radviz(iris,S)
plot(rv,anchors.only=FALSE)
new.S <- do.optimFreeviz(x = iris[,das], classes = iris$Species)
new.rv <- do.radviz(iris,new.S)
plot(new.rv,anchors.only=FALSE)
plot(anchor.filter(new.rv,0.2))
