reidx.cut: re-index cut(ree) vector
In bennop/clusterLUTs: Color lookup ables for use with hierarchical clustering

Description Usage Arguments Details Value Author(s) Examples

Internal rank increasing within ties so that after reordering the order of ties can be preserved

1	reidx.cut(cut)

cut

cut from hierarchical clustering (through link[stats]{cutree})

the output vector is named with (original level + position as decimal fraction) with ties for that level, see example. this can handles multiplicities of up to 999 which should suffice for most practical cases.

This is useful to reorder, e.g., a color LUT from color.shades according to levels.

rank vector with names to indicate level and order within ties
