DescriptionUniform Manifold Approximation and Projection (UMAP) is an algorithm for dimensional reduction. Its details are described by McInnes, Healy, and Melville and its official implementation is available through a python package umap-learn. The R package umap described in this vignette is a separate work that provides two implementations for using UMAP within the R environment. One implementation is written from-scratch and another links to the official umap-learn. (Another R package, uwot, provides a separate implementation with a slightly different interface).
