vec_sample: Re-implementation of 'base::sample()' Using the vctrs Package

In jesse-smith/coviData: COVID-19 Data Munging Tools for the Shelby County Health Department

Re-implementation of base::sample() Using the vctrs Package

Description

sample() behaves unexpectedly when called on objects other than atomic vectors. This re-implementation has identical logic but uses the vctrs package to generalize to other inputs. Parameters are modeled after slice_sample().

Usage

vec_sample(.x, n, replace = FALSE, weight_by = NULL)

Arguments

.x	The data to sample
n	The number of samples to return
replace	Should sampling be performed with (TRUE) or without (FALSE, the default) replacement?
weight_by	Sampling weights. This must evaluate to a vector of non-negative numbers the same length as the input. Weights are automatically standardised to sum to 1.
