Compute the number of elements less or equal the elements in a given vector.
Arguments
- x
a numeric vector.
- ox
order(x), optionally (for efficiency in case
order(x) is already known).
Value
A vector of integers.
Examples
x <- rnorm(10)
irank(x)
#> [1] 1 9 7 4 8 3 2 5 6 10
rank(x)
#> [1] 1 9 7 4 8 3 2 5 6 10
x <- c(1,2,3,3,0)
irank(x)
#> [1] 2 3 5 5 1
rank(x)
#> [1] 2.0 3.0 4.5 4.5 1.0
