find_breaks

Breakpoints to be passed to a Histogram

Description

The function find_breaks() isolates a piece of code of the function truehist() from package MASS that is used to compute the set of breakpoints to be applied for the construction of the histogram.

Usage

find_breaks(x, nbins = "Scott", h, x0 = -h/1000)

Arguments

x

numeric. A vector.
nbins

integer or character. The suggested number of bins. Either a positive integer, or a character string naming a rule: "Scott" (the default) or "Freedman-Diaconis" or "FD". (Case is ignored.)
h

numeric. The bin width, a strictly positive number (takes precedence over nbins).
x0

numeric. Shift for the bins - the breaks are at x0 + h * (..., -1, 0, 1, ...).
