tabulating 2 factors weighting by a third var
...a table such that v1 levels will show as rows, v2 levels as columns and v3 is the weight by which table(v1,v2) is weighted? 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?

monthly median in a daily dataset
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) )
