Equal length binning — rbin_equal

Bin continuous data using the equal length binning method.

rbin_equal_length(
  data = NULL,
  response = NULL,
  predictor = NULL,
  bins = 10,
  include_na = TRUE
)

# S3 method for rbin_equal_length
plot(x, print_plot = TRUE, ...)

Arguments

data	A `data.frame` or `tibble`.
response	Response variable.
predictor	Predictor variable.
bins	Number of bins.
include_na	logical; if `TRUE`, a separate bin is created for missing values.
x	An object of class `rbin_equal_length`.
print_plot	logical; if `TRUE`, prints the plot else returns a plot object.
...	further arguments passed to or from other methods.

Value

A tibble.

Examples

bins <- rbin_equal_length(mbank, y, age, 10)
