show.colmat: show color matrix

In bennop/clusterLUTs: Color lookup ables for use with hierarchical clustering

Description

Show colors represented in color vector cv as matrix of colored boxes.

Usage

show.colmat(cv, width = NULL, show.idx = FALSE, ...)

Arguments

cv	color vector (actually 3xn matrix with one column per color (RGB))
width	how many color tiles across (~sqrt(n) where n is the length of the color vector)
show.idx	add index to display
...	passed to rect

Details

By setting show.idx to TRUE, the index in the color vector is shown in the center of the color tiles. Assigning a vector the same length as cv, the elements of that vector will be shown rather than the index.

Value

none
