This function provides a logical test of whether or not a vector is a constant.
is.constant(x)
x |

As opposed to a variable, a constant is a vector in which the elements contain less than or equal to one unique value.
The is.constant function returns a logical result, reporting
TRUE when a vector is a constant, or FALSE otherwise.
