all_same {str2str}

Test if All Elements are the Same

Description

all_same tests if all elements are the same. 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_same(x)

Arguments

x

atomic vector, list vector, or list.

Details

The machine precision of all_same 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_same(rep.int("a", times = 10))
all_same(rep.int(1, times = 10))
all_same(c(1.0000000, 1.0000001, 0.9999999)) # machine precision good for most cases
all_same(1) # works for vectors of length 1
