Hi all
I'm happy to announce the availability of the aggregation package.
https://github.com/tbanel/orgaggregate
Example:
This is a source table:
#+TBLNAME: source
| Day | Quantity |
|-----------+----------|
| Monday | 10 |
| Monday | 3 |
| Tuesday | 52 |
| Tuesday | 15 |
| Tuesday | 18 |
| Wednesday | 100 |
| Wednesday | 23 |
| Wednesday | 16 |
This is an aggregated result computed by the package:
#+BEGIN: aggregate :table source :cols "Day sum(Quantity)"
| Day | sum(Quantity) |
|-----------+---------------|
| Monday | 13 |
| Tuesday | 85 |
| Wednesday | 139 |
#+END:
For those familiar with SQL, this is reminicent of the GROUP BY statement.
For those familiar with the R statistics, this is reminicent of FACTORS.
Features include:
- Pure Emacs (no external dependency)
- Wide variety of aggregation functions (sum, mean, max, count, median,
etc.)
- Calc underlying engine (the same used by Org spreadsheet)
- Work in push or pull mode (pull mode uses so called dynamic blocks)
- Any combination of key columns
- and more
To use it:
- load in Emacs
https://github.com/tbanel/orgaggregate/blob/master/org-aggregate.el
This give access to the command:
M-x org-insert-dblock:aggregate
- look at the examples and documentation here:
https://github.com/tbanel/orgaggregate
- optionally load
https://github.com/tbanel/orgaggregate/blob/master/org-insert-dblock.el
This gives the following key-binding:
C-c C-x i
which insert any kind of dynamic blocks, including "aggregate"
Feedback welcome.
Have fun
Thierry
