dist_extract: Extract distances between specified indexes from a 'dist'...

In talegari/forager: Compute auxiliary information (proximity, dissimilarity, outlyingness, depth) and imputation from tree ensembles on new data

Description

Extract distances as a vector when product is inner and as a matrix when the product is outer

Usage

dist_extract(object, i, j, product = "inner")

Arguments

object	distance object
i	index
j	index. If missing, this defaults to 1:size of the dist object
product	(string) product type. One among: 'inner', 'outer'.

Details

When j is missing, it defaults to 1:size of the dist object. When the product is inner and lengths of i and j mismatch, the smaller one is extended to the size of the onger one.

Value

A vector of distances when 'inner' is used. A matrix of distances when 'outer' is used.

Examples

temp <- stats::dist(datasets::mtcars)
dist_extract(temp, 1:2, 3:5, "inner")
dist_extract(temp, 1:2, 3:5, "outer")
