NAME Array::Sample::SimpleRandom - Sample elements randomly (with or without replacement) VERSION This document describes version 0.003 of Array::Sample::SimpleRandom (from Perl distribution Array-Sample-SimpleRandom), released on 2022-05-21. SYNOPSIS use Array::Sample:: qw(sample_simple_random_with_replacement sample_simple_random_no_replacement); sample_simple_random_with_replacement([0,1], 1); => (0) sample_simple_random_with_replacement([0,1], 3); => (0,1,0) sample_simple_random_no_replacement([0,1,2,3,4], 1); => (3) sample_simple_random_no_replacement([0,1,2,3,4], 3); => (2,1,4) sample_simple_random_no_replacement([0,1,2,3,4], 7); => (3,4,2,1,0) DESCRIPTION FUNCTIONS All functions are not exported by default, but exportable. sample_simple_random_with_replacement Syntax: sample_simple_random_with_replacement(\@ary, $n [ , \%opts ]) => list Options: * pos => bool If set to true, will return positions instead of the elements. The function takes an array reference ("\@ary") and number of samples to take ($n). It will take samples at random position. An element can be picked more than once. sample_simple_random_no_replacement Syntax: sample_simple_random_no_replacement(\@ary, $n [ , \%opts ]) => list Options: * pos => bool If set to true, will return positions instead of the elements. The function takes an array reference ("\@ary") and number of samples to take ($n). It will take samples at random position. An element can only be epicked once. If $n is larger than the number of elements in the array, only that many elements will be taken. The implementation constructs a (shallow) copy of the array then remove elements randomly from the copy-array until the number of requested samples are met. There is another implementation that avoids creating a copy but scans the array once; see Array::Sample::SimpleRandom::Scan. HOMEPAGE Please visit the project's homepage at .

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via: % prove -l If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required beyond that are considered a bug and can be reported to me. COPYRIGHT AND LICENSE This software is copyright (c) 2022 by perlancar .
