find.ab.params: Estimate a/b parameters

In donelsonsmith/umap_R: Uniform Manifold Approximation and Projection

Description

This performs a brute-force search in parameter space. The algorithm assumes a narrowing-down search will produce a decent fit.

Usage

find.ab.params(spread, min.dist, alim = c(0, 20), blim = c(0, 20),
  tolerance = 1e-08)

Arguments

spread	numeric
min.dist	numeric
alim	numeric vector of length 2, initial search range for parameter a
blim	numeric vector of length 2, initial search range for parameter b
tolerance	numeric, determines how deeply to search

Value

vector with componets "a" and "b" that are most appropriate for the given spread and min.dist.
