all_diff

Test if All Elements are Different

Description

all_diff tests if all elements are different. The elements could be either from an atomic vector, list vector, or list. If x does not have any unique values (e.g., NULL), then FALSE is returned.

Usage

all_diff(x)

Arguments

`x`	atomic vector, list vector, or list.

Details

The machine precision of all_diff for numeric vectors is the same as unique. This can causes a problem for some floating-point numbers.

Value

logical vector of length 1 specifying whether all the elements in x are the same (TRUE) or not (FALSE).

Examples

all_diff(1:10)
all_diff(c(1:10, 10))
all_diff(c(1.0000000, 1.0000001, 0.9999999)) # machine precision good for most cases
