ORDER is a generic function for computing ordering
permutations.
Usage
ORDER(x, ...)
## S3 method for class 'default':
ORDER(x, \dots, na.last = TRUE, decreasing = FALSE)
Arguments
x
an object.
...
further arguments to be passed to methods.
na.last
for controlling the treatment of NAs.
If TRUE, missing values in the data are put last; if
FALSE, they are put first; if NA, they are removed.
decreasing
logical. Should the sort order be increasing or
decreasing?
Details
ORDER is a new generic function which aims at providing
the functionality of the non-generic base function order
for arbitrary objects. Currently, there is only a default method which
simply calls order.
