percentify_cut: Group a data.frame by percentile ranges in variable by...

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

Description

This function is a small wrapper around percentify. This function takes a vector of points and creates ranges between those points, resulting in non-overlapping groups.

Usage

percentify_cut(data, var, q = numeric())

Arguments

data	A data.frame or tibble,
var	Variable to do grouping by as string or symbol.
q	Numerical values for cutting points. Must be between 0 and 1.

Details

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

Value

percentile grouped tibble

See Also

cut_evenly

Other percentile samplers: autoplot.percentiled_df, percentify_max, percentify_min, percentify_random

Examples

library(dplyr)
library(broom)
percent_mtcars <- percentify_cut(mtcars, mpg, c(0.25, 0.5, 0.75))

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)))

# cut_evenly() can be used to create cuts
percentify_cut(mtcars, mpg, cut_evenly(8))

library(ggplot2)
autoplot(percent_mtcars)
