R: Register Seriation Based on 1D UMAP

register_umap {seriation} | R Documentation

## 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.

    d <- dist(random.robinson(50, pre=TRUE, noise=.1))

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