rank.integer64: Sample Ranks from integer64

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

Description

Returns the sample ranks of the values in a vector. Ties (i.e., equal values) are averaged and missing values propagated.

Usage

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

Arguments

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

Details

This function automatically chooses from several low-level functions considering the size of x and the availability of a cache. Suitable methods are sortorderrnk (fast ordering) and orderrnk (memory saving ordering).

Value

A numeric vector of the same length as x.
