That is, instead of getting the count of occurences in each of the 10 cells of table(v1,v2) I would like to get the sum(v3), how can it be done?

Hello, I have a multi-year dataset (see below) with date, a data value and a flag for the data value. I want to find the monthly median for each month in this dataset and then plot it. If anyone has suggestions they would be greatly apperciated. It should be noted that there are some dates with no values and they should be removed. Thanks Emily > print ( str(data$flow$daily) )
