Sample Ranks from integer64

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

Value

A numeric vector of the same length as x.

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)

• orderrnk() (memory saving ordering).

See also

order.integer64(), rank() and prank() for percent rank.

Examples

x <- as.integer64(sample(c(rep(NA, 9), 1:9), 32, TRUE))
rank.integer64(x)
#>  [1] 16.0 11.5  1.5  6.0   NA 11.5 19.5  4.0 19.5   NA 21.0 16.0 11.5   NA
#> [15]   NA 16.0  8.5   NA   NA  8.5 11.5   NA  1.5   NA   NA 16.0   NA  4.0
#> [29]  7.0 16.0   NA  4.0
