org tables and R

Hi all,

I've had a go at taking the org tables and R thing a bit further. I'm
using two different #+ lines in the org buffer: Lines starting with
#+TBLR: are in the standard org style (option:value) and can be used
to specify certain transformations of the table and standard plots of
the table data. In lines starting #+TBLR:: you can supply literal R
code, giving you full control over what you do with the table. M-x
org-table-R-apply makes happen whatever has been specified in those
lines. As long as the transformation results in something reasonably
one- or two-dimensional, then this is output to the org-buffer as an
org table (you can choose whether or not it replaces the original
table). You need to have R running in an inferior-ess-mode
buffer. Then, if you have this table,

| rowname | col1 | col2 |
|---------+------+------|
| row 1   |    1 |    2 |
| row 2   |    3 |    4 |
| total   |      |      |
#+TBLR:: x[3,] <- x[1,] + x[2,]
#+TBLR: rownames:1

org-table-R-apply turns it into 

| rownames(x) | col1 | col2 |
|-------------+------+------|
| row 1       |    1 |    2 |
| row 2       |    3 |    4 |
| total       |    4 |    6 |
