Hi Jason,

Thanks for the clear example.

While we're talking about this particular problem, I thought I'd mention
that there's also a nice off-the-shelf solution in R:

#+tblname: daily-expenses
| Expense | Category |
|---------+----------|
|       2 | Food     |
|       1 | House    |
|      10 | Clothes  |
|       3 | Food     |
|       5 | House    |

#+begin_src R :var tab=daily-expenses :colnames yes
  attach(tab)
  aggregate(Expense ~ Category, FUN=sum)
#+end_src

#+results:
| Category | Expense |
|----------+---------|
| Clothes  |      10 |
| Food     |       5 |
| House    |       6 |

Dan
