Objectives

Import data into R from org

Org-mode includes orgtbl-mode, an extremely convenient way of using tabular data in a plain text file. Currently, spreadsheet functionality is available in org tables using the emacs package calc. It would be a boon both to org users and R users to allow org tables to be manipulated with the R programming language. Org tables give R users an easy way to enter and display data; R gives org users a powerful way to perform vector operations, statistical tests, and visualization on their tables.

Implementations

naive

Naive implementation would be to use (org-export-table "tmp.csv") and (ess-exec "read.csv('tmp.csv')").

Editing R code using r-mode from an org buffer

Org has an extremely useful method of editing source code and examples in their native modes. In the case of R code, we want to be able to use the full functionality of ESS mode, including interactive evaluation of code.

Implementations

Org

#+BEGIN_SRC r

,## hit C-c ' within this block to enter a temporary buffer in r-mode.

,## while in the temporary buffer, hit C-c C-c on this comment to
,## evaluate this block
a <- 3
a

,## hit C-c ' to exit the temporary buffer
