construct a umap.knn object describing nearest neighbors
umap.knn(indexes, distances)
indexes |
matrix, integers linking data points to nearest neighbors |
distances |
matrix, distance values between pairs of points specified in the matrix of indexes |
object of class umap.knn, which is a list with matrices with indexes of nearest neighbors and distances to those neighbors
# this example describes a set of three data points (indexes 1,2,3)
# which are equidistant from each other. Hence the distance between
# pairs (i, j) is 0 for i=j and 1 otherwise.
three.indexes = matrix(c(1,2,3,
