Quantile Summaries

Description

Return quantile summary (minimum, quantiles, maximum) for the input data.

Usage

midpoints(x, n = 1, na.rm = TRUE)

Arguments

x

numeric, maybe including NAs and +/-Infs.

n

positive integer, to determine which quantiles to calculate. return values are 2 ^ n + 1 number summary. n=1 (default) is for three number, namely, minimum, median and maximum. n=2 is for five number, such as quartiles. n=3 is for nine number, such as octiles.

na.rm

logical value indicating whether NAs should be stripped before the computation proceeds.

Details

This function is calling midpoint with n depth.

Value

A numeric vector of length 2 ^ n + 1 containing the summary information.
