Compute ranks
xrank(x, best = TRUE, na.rm = FALSE)vector of values to be ranked
logical; if TRUE (default), the rank of the j-th element is defined as the number of other elements strictly larger than the j-th. Otherwise, the rank is defined as the number of other elements strictly smaller than the j-th.
logical; if TRUE, then NA's are removed from x (if any).
vector of the same dimension as x containing the ranks
xrank(c(4,4,4,3,1,10,7,7))
#> [1] 4 4 4 7 8 1 2 2
