seriation (version 1.3.1)

register_umap: Register Seriation Based on 1D UMAP

Description

Use uniform manifold approximation and projection (UMAP) to embedd the data on the number line and create a seriation order.

Usage

register_umap()

Details

Registers the method "umap" for seriate. This method applies 1D UMAP to data represented by a distance matrix and extracts the order from the 1D embedding.

Note: Package umap needs to be installed.

o <- seriate(d, method = "umap")
pimage(d, o)
