quadtrafo {klaR} | R Documentation

## Transforming of 4 dimensional values in a barycentric coordinate system.

### Description

Transforming of 4 dimensional values in a barycentric coordinate system.

### Usage

    quadtrafo(e, f = NULL, g = NULL, h = NULL)

    quadlines(e, f = NULL, g = NULL, h = NULL, sp, ...)

    quadpoints(e, f = NULL, g = NULL, h = NULL, sp, ...)

### Arguments

`e` | either a matrix with 4 columns represanting the membership values or a vector with the membership values of the first class
`f` | vector with the membership values of the second class
`g` | vector with the membership values of the third class
`h` | vector with the membership values of the forth class
`sp` | `scatterplot3d` object to which `points` or `lines` should be plotted
`...` | further arguments passed to the underlyind `plot` functions

### Value

For `quadtrafo` the 3 dimensional values in the barycentrix coordinate system.
