    Reduce the given column of values to a cell using only the indexes in given array slice.

    Reduce the given column of values to a cell using only the indexes in given array slice.

    indices, start, and end represent an array slice. The following must hold:

    • 0 <= start
    • end <= indices.length
    • start <= end

    and the slice is [start:end), inclusive of start and exclusive of end.

    Let i: Int where start <= i and i < end, then

    column(indices(i)) match {
    case Value(v) => // 1.
    case NA => // 2.
    case NM => // 3.
}
    1. In the case of a Value, the value should be included in the reduction.
    2. In the case of NA, the reduction should skip.
    3. In the case of NM, the reduction should terminate with NM.
    column

    the column of values is the source of the reduction

    indices

    the array of column indexes to reduce over

    start

    the start of the array slice on the indices

    end

    the end of the array slice on the indices

    returns

    the result of the reduction as a Cell
