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

Cluster Lookup Tables - cluster LUTs

Coloring for a cluster tree with 145 leaves and 28 levels (10 (top), 15, ..., 145 clusters (bottom)):

basedir <- ifelse(basename(getwd()) == 'docs',
                  'reference',
                  'docs/reference')
cat(sprintf("![colortree](%s/colortree.png)", basedir))

Concepts

A hue range specifies a range or set of ranges in hue space ([0..1]). In sets the hue ranges need not be disjunct but usually are in the context of this package.

A tree range is a hierarchical collection of hue ranges where each level corresponds to one level of clustering.

A color matrix is a 3xn matrix specifying RGB colors (like the output of col2rgb)

Generation

• hue.range.split
• tree.ranges

Output

• hue.range.lines
• tree.range.plot
