In baslat/sak: The Swiss Army Knife of R

Sample complete groups from a grouped tibble

Description

This function lets you sample groups from a grouped tibble. The default behaviour of sample() on a grouped tibble is to sample within each group, but sometimes you want to sample a few complete groups. This lets you do that.

Usage

sample_groups(grouped_df, n, replace = FALSE)

Arguments

grouped_df	(grouped tibble) a grouped tibble from which you want to sample groups
n	(number) how many groups do you want?
replace	(boolean; default = FALSE) sample with replacement?

Details

Doesn't work with sfs because of the geometry column.

Value

a grouped tibble containing n groups from the original data

Examples

dplyr::storms %>%
  dplyr::group_by(name) %>%
  sample_groups(2)
