Mode finds the most common values in a vector. If one value occurs more often than any other value in the vector, a vector of that one value is returned. If there are two or more values that "tie" for the most common value, a vector of all those values is returned. If no values are passed in to mode, the empty vector is returned. Thus, mode always returns a vector.

Mode accepts a vector of non-numbers as well.

number.<mode _other_unkeyed=<v "red" "green" "green" "red" "blue"/>/>

<vector "green" "red"/>

You can also pass in _other_keyed args to mode. Thus neither the keys nor the values of fields need be numeric for mode to find the most common values.

number.<mode _other_keyed=<thing a="aa" b="bb" c="aa" d="bb" e="x"/>/>

<vector "aa" "bb"/>

The resulting vector is sorted to have the lowest numbers and the lexically first elements first.
