HistogramTools (version 0.3.2)

SubsetHistogram: Subset a histogram by removing some of the buckets.

Description

SubsetHistogram creates a histogram by zooming in on a portion of a larger histogram and discarding tail buckets.

Usage

SubsetHistogram(x, minbreak=NULL, maxbreak=NULL)

Arguments

x

A histogram object (created by hist).

minbreak

If non-NULL, specifies a new minimum breakpoint for the returned histogram. Must be one of the existing breakpoints of x.

maxbreak

If non-NULL, specifies a new maximum breakpoint for the returned histogram. Must be one of the existing breakpoints of x.

Details

This function provides a way to "zoom-in" on a histogram by setting new minimum and maximum breakpoints and returning a histogram of only the interior part of the distribution. At least one of minbreak or maxbreak should be set, otherwise the original histogram is returned unmodified.
