EmbedSOM (version 2.2)

UMatrixCoords: Add U-Matrix-optimized embedding coordinates to the map

Description

The map must already contain a SOM grid with corresponding xdim,ydim (possibly zdim)

Usage

UMatrixCoords(
  dim = NULL,
  dist.method = NULL,
  distFn = function(x) x,
  layoutFn = igraph::layout_with_kk
)

Value

a function that transforms the map, usable as 'coordsFn' parameter

Arguments

dim

Dimension of the result (passed to layoutFn)

dist.method

The method to compute distances, passed to stats::dist() as parameter method

distFn

Custom transformation function of the distance matrix

layoutFn

iGraph-compatible graph layouting function (default igraph::layout_with_kk)
