computeRandomSelection {coreCollection}R Documentation

Compute a random selection

Description

The function computeRandomSelection is used internally by the CoreCollection object.

Usage

computeRandomSelection(dist, requiredN, preselected, seed)

Arguments

dist

distance matrix, used for distances and implicitly defining the set of entries

requiredN

the required size of the random selection

preselected

a list of preselected entries, referring to the row/column of dist

seed

the applied seed for the randomizer

Details

This function returns a random selection of approximately size requiredN by choosing entries sequentually and randomly, while excluding all entries within a certain radius of an entry chosen before, and by finding iteratively the most appropiate radius to end up with a number close to requiredN of selected entries.
