Returns the sample ranks of the values in a vector. Ties (i.e., equal values) are averaged and missing values propagated.
# S3 method for integer64
rank(x, method = NULL, ...)A numeric vector of the same length as x.
a integer64 vector
NULL for automatic method selection or a suitable low-level method, see details
ignored
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).
order.integer64(), rank() and prank() for percent rank.
x <- as.integer64(sample(c(rep(NA, 9), 1:9), 32, TRUE))
rank.integer64(x)
stopifnot(identical(rank.integer64(x), rank(as.integer(x)
, na.last="keep", ties.method = "average")))
