In EmilHvitfeldt/percentify: Splitting a Dataset According to Percentile Ranges

Description

This function is a wrapper around percentify. Given a width`` and a n', it will generate a number of random interval with fixed width.

Usage

percentify_random(data, var, width, n = 10)

Arguments

data	A data.frame or tibble,
var	Variable to do grouping by as string or symbol.
width	Numerical values for the width of the interval. Must be between 0 and 1.
n	Integer, number of intervals to create.

Details

There is a ggplot2::autoplot() to visualize the the percentile ranges.

Value

percentile grouped tibble

Examples

library(dplyr)
library(broom)
set.seed(1234)
percent_mtcars <- percentify_random(mtcars, mpg, 0.4, 10)

percent_mtcars

summarize(percent_mtcars,
          mean_hp = mean(hp),
          mean_wt = mean(wt),
          n_obs = n()
          )

percent_mtcars %>%
  group_modify(~tidy(lm(disp ~ wt + cyl, data = .x)))

library(ggplot2)
