Set up bootstrap replicates of a dplyr operation

Source: R/bootstrap.R

The bootstrap() function is deprecated and will be removed from an upcoming release of broom. For tidy resampling, please use the rsample package instead.

bootstrap(df, m, by_group = FALSE)

Arguments

df

a data frame
m

number of bootstrap replicates to perform
by_group

If TRUE, then bootstrap within each group if df is a grouped tbl.

Examples


if (FALSE) {
library(dplyr)
mtcars %>% bootstrap(10) %>% do(tidy(lm(mpg ~ wt, .)))
}
