|See also: SumOfNumCells, CountValidCells, CountEmptyCells, CountImputedCells|
The function CountNumCells counts all data cells within a specified range of cells which are neither marked as csNAN, nor as csUndefined and which belong to either interval or ratio scaled variables (that is, all cells which contain "real" numbers). The range of the data table elements to be counted is determined by the parameters LowRow, LowCol, HighRow, and HighCol. If any of these parameters receives an invalid value, this value is automatically adjusted to the nearest boundary value (either 1 or NrOfColumns / NrOfRows).
The function returns the number of valid, non-empty, non-categorical data cells within the specified range.
