prank: (P)ercent (Rank)s

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

(P)ercent (Rank)s

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

Details

Function prank.integer64 is based on rank.integer64().

Value

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

See Also

rank.integer64() for simple ranks and qtile() for the inverse function quantiles.

Examples

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

x <- x[!is.na(x)]
stopifnot(identical(x,  unname(qtile(x, probs=prank(x)))))
