Unique(vector, [type])

Searches a column (array or range) for unique values.

If 'type' is 0, the 'unique' function returns a vector of indices to the subsequent unique values found in 'vector'.

If 'type' is 1, the 'unique' function returns a vector of unique values found in 'vector'.

If 'type' is 2, the 'unique' function returns a two-column array.
The first column contains unique values, the second one: the number of occurrences of the corresponding value.

If 'type' is omitted, it's assumed to be 1.

Unique() examples:

=unique({2; 3; 1; 2; 5; 3; 1}, 1) returns {1; 2; 3; 5}

=unique({"a"; "b"; "cd"; "a"; "cd"; "b"; "d"}, 0) returns {1; 2; 3; 5}

=unique({"a"; "b"; "cd"; "a"; "cd"; "b"; "d"}, 2) returns { "a", 2; "b", 2; "cd", 2; "d", 1}

You can insert the Unique() function with just two clicks using the Insert > UNIQUE() command. The displayed "Insert UNIQUE()" dialog box determines the optimum parameters including the option to copy styles from the selected source data range and automatically creates the formula.
