Test if a vector-like object is not sorted

Description

Test if a vector-like object is not sorted, without the cost of sorting it.

NOTE: This man page is for the is.unsorted S4 generic function defined in the BiocGenerics package. See ?base::is.unsorted for the default method (defined in the base package). Bioconductor packages can define specific methods for objects (typically vector-like) not supported by the default method.

Usage

is.unsorted(x, na.rm=FALSE, strictly=FALSE, ...)

Arguments

Value

See ?base::is.unsorted for the value returned by the default method.

Specific methods defined in Bioconductor packages should behave as consistently as possible with the default method.

Note

TO DEVELOPERS:

The is.unsorted method for specific vector-like objects should adhere to the same underlying order used by the order, sort, and rank methods for the same objects.
