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

Description

This function is a small wrapper around percentify, where the upper bound is a fixed value.

Usage

percentify_min(data, var, q = numeric(), lower = 0)

Arguments

data	A data.frame or tibble,
var	Variable to do grouping by as string or symbol.
q	Numerical values for upper bound of ranges. Must be between 0 and 1.
lower	Numerical values for lower bound of ranges. Must be between 0 and 1. Length of lower and upper must be equal.

Details

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

Value

percentile grouped tibble

          mean_wt = mean(wt),
