* Introduction
  The Library of Babel is an extensible collection of ready-made and
  easily-shortcut-callable source-code blocks for handling common
  tasks.  Org-babel comes pre-populated with the source-code blocks
  located in this file. It is possible to add source-code blocks from
  any org-mode file to the library by calling =(org-babel-lob-ingest
  "path/to/file.org")=.

* Plotting code

** R
  Plot column 2 (y axis) against column 1 (x axis). Columns 3 and beyond, if present, are ignored.

#+srcname: R-plot(data=R-plot-example-data)
