breaks

Description

Creates a number of equidistant or non-equidistant breaks for given data x. If width is not given then it will be set to diff(pretty(x))[1]. probs can either be a single integer giving the number of quantiles or a vector of probabilities with values in [0,1]. Note that if width is too large then using probs may result in equidistant breaks, too.

Usage

breaks(x, width = NULL, probs = NULL)

Arguments

x	numeric: data
width	numeric: class width (default: NULL)
probs	numeric: number of non-equidistant classes (default: NULL)

Value

a numeric vector of breaks

Examples

x <- rnorm(100, mean=1.8, sd=0.1)
breaks(x)
breaks(x, 0.1)
breaks(x, 0.1, probs=4)
