Two-argument form See also Not
Without is used to remove items from a vector. Items in its left argument which are found in its right argument are removed from the result. When the arguments are nested, an exact match in data and structure must be found before an item is removed. The right argument can be of any shape of rank. This operation is affected by ŒCT, the comparison tolerance.
