cut_interval: Cut up numeric vector into useful groups.

Description

cut_interval makes n groups with equal range, cut_number makes n groups with (approximately) equal numbers of observations; cut_width makes groups of width width.

Usage

cut_interval(x, n = NULL, length = NULL, ...)
cut_number(x, n = NULL, ...)
cut_width(x, width, center = NULL, boundary = NULL, closed = c("right",
  "left"))

Arguments

x

numeric vector

n

number of intervals to create, OR

length

length of each interval

...

other arguments passed on to cut

width

The bin width.

center, boundary

Specify either the position of edge or the center of a bin. Since all bins are aligned, specifying the position of a single bin (which doesn't need to be in the range of the data) affects the location of all bins. If not specified, uses the "tile la

closed

One of "right" or "left" indicating whether right or left edges of bins are included in the bin.
