In sigbertklinke/smvgraph: Visualization and Clustering of Data in a Shiny App

sdistance

Description

Shiny app which shows the contribution of each variable to the distance between two observations with interactive variable selection. If dijk is the distance between observations i and j in variable k then the contribution is computed:

Usage

sdistance(data, xvar = character(0), ...)

Arguments

data	matrix or data.frame
xvar	character: names of selected variables for the plot
...	unused

Details

• Total variance: var_k/sum(var_k) with var_k the variance of the kth variable

• Minimum: dijk==min_k(dijk)

• Manhattan: dijk/sum(dijk)

• Gower: dijk is rescaled to [0, 1] in each variable and then dijk/sum(dijk)

• Euclidean: dijk^2/sum(dijk^2)

• Manhattan: dijk/sum(dijk)

• Maximum: dijk==max_k(dijk)

Value

nothing

Examples

if (interactive()) sdistance(iris)
