Plotting paintmaps
Description
Plots matrices of colours as grids of coloured squares - aka heatmaps, guaranteeing legible row and column names, without transformation of values, without re-ordering rows or columns, and without dendrograms.
Details
The function ‘bhm’ takes a matrix of colours (i.e. a character matrix of descriptions like red or hex-codes), and creates a plot using ‘grid’ graphics.

Usage
color_matrix(x, colors = heat.colors(10))
Arguments
x |
Numeric or logical matrix. |
colors |
Character vector of colors. |
Value
Character matrix.
