Splitting up large set of survey data into categories
...if the dates are displayed as weeks, doesn't
aggregate the values immediately. Unfortunately there seems to be no command
which works exactly in the same manner as by() (from stata) in R. My by now
most successful attempt accomplish the above described task was by using:

(where date is formatted as ISO-weekly %U)
Of course I would have to loop this over all questions (20) and all
answering possibilities (3) but at least it gives me an out put of the
structure:
.
industry.region
Industry....
