Members

MemberDescription
AvgReturns the average of cells in a range.
CountCounts the number of cells in a range that contain numbers.
CountACounts the number of cells in a range that are not empty.
CustomCustom aggregation.
MaxReturns the maximum value of cells in a range.
MinIndicates that rowCount of the cells in the specified range of cells.
NoneIndicates that does't support aggregation for the sheet.
ProductMultiplies all the cells in a range and returns the product.
StDevReturns the standard deviation for a set of cells in a range.
StDevPCalculates standard deviation based on the entire population given as cells in a range.
SumSums values of cells in a range.
VarCalculates variance based on a sample of a population.
VarPCalculates variance based on the entire population.
