ORDER {zoo} | R Documentation |
ORDER
is a generic function for computing ordering
permutations.
ORDER(x, ...)
## Default S3 method:
ORDER(x, ..., na.last = TRUE, decreasing = FALSE)
x |
an object. |
... |
further arguments to be passed to methods. |
na.last |
for controlling the treatment of |
decreasing |
logical. Should the sort order be increasing or decreasing? |
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
. For objects (more precisely if
is.object
is TRUE
) order
leverages the generic xtfrm
. Thus, to assure ordering
works, one can supply either a method to xtfrm
or to ORDER
(or both).
ORDER(rnorm(5))
