Test if an Object is Not Sorted
Description
Test if an object is not sorted, without the cost of sorting it.
Usage
is.unsorted(x, na.rm = FALSE, strictly = FALSE)
Arguments
x |
an R object with a class or a numeric, complex, character or logical vector. |
na.rm |
logical. Should missing values be removed before checking? |
strictly |
logical indicating if the check should be for strictly increasing values. |
Value
A length-one logical value. All objects of length 0 or 1 are sorted:
the result will be NA for objects of length 2 or more except for
atomic vectors and objects with a class (where the >= or >
method is used).
