R: Sample Ranks from integer64

rank.integer64 {bit64} | R Documentation

## Sample Ranks from integer64

### 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`.

### Examples

    x <- as.integer64(sample(c(rep(NA, 9), 1:9), 32, TRUE))
    rank.integer64(x)

    stopifnot(identical(rank.integer64(x),  rank(as.integer(x)
    , na.last="keep", ties.method = "average")))
