ORDER: Ordering Permutation

In zoo: S3 Infrastructure for Regular and Irregular Time Series (Z's Ordered Observations)

Ordering Permutation

Description

ORDER is a generic function for computing ordering permutations.

Usage

ORDER(x, ...)
## Default S3 method:
ORDER(x, ..., 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. 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).
