prank: (P)ercent (Rank)s

In truecluster/bit64: A S3 Class for Vectors of 64bit Integers

Description

Function prank.integer64 projects the values [min..max] via ranks [1..n] to [0..1]. qtile.integer64 is the inverse function of 'prank.integer64' and projects [0..1] to [min..max].

Usage

	prank(x, ...)
	## S3 method for class 'integer64'
prank(x, method = NULL, ...)

Arguments

x	a integer64 vector
method	NULL for automatic method selection or a suitable low-level method, see details
...	ignored

Details

Function prank.integer64 is based on rank.integer64.

Value

prank returns a numeric vector of the same length as x.
