Sample Ranks, Including Rvecs

Calculate sample ranks for ordinary vectors or for rvecs. In the case of rvecs, ranks are calculated independently for each draw.

Usage

rank(
  x,
  na.last = TRUE,
  ties.method = c("average", "first", "last", "random", "max", "min")
)

Arguments

x

An ordinary vector or an rvec().

na.last

Treatment of NAs. Options are TRUE, FALSE, or "keep". See base::rank() for details.

ties.method

Treatment of ties. See base::rank() for details.

Value

An rvec if x is an rvec, otherwise an ordinary numeric vector. Average ranks are doubles, allowing fractional ranks for ties; other tie methods return integer ranks.

Details

To enable different behavior for rvecs and for ordinary vectors, the base R function base::rank() is turned into a generic, with base::rank() as the default.

For details on the calculations, see the documentation for base::rank().

Examples

x <- rvec(list(c(3, 30),
               c(0, 100)))
rank(x)
#> <rvec_dbl<2>[2]>
#> [1] 2,1 1,2
