In iaaka/visutils: QC, analyse and visualize visium

Maps distance matrix into colour space

Description

use MDS (via cmdscale) to map objects into colour space

Usage

getColoursByDistance(d, use3D = FALSE, orderBySim = FALSE)

Arguments

d	distance matrix to be used with MDS
use3D	logical, specifies whether whole 0,1^3 space should be used. About equally-bright 2D space is used otherwise (default)
orderBySim	logical, whether objects should be ordered by similarity. Preserves original order otherwise (default)

Value

vector of colors

Examples

d=1-cor(t(mtcars))
c=getColoursByDistance(d,F)
plot(cmdscale(d),col=c,pch=19)
