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")=. This file is included in worg mainly less for viewing through the web interface, and more for contribution through the worg git repository. If you have code snippets that you think others may find useful please add them to this file and [[file:~/src/worg/worg-git.org::contribute-to-worg][contribute them]] to worg. The raw Org-mode text of this file can be downloaded at [[repofile:contrib/babel/library-of-babel.org][library-of-babel.org]] * Plotting code ** R Plot column 2 (y axis) against column 1 (x axis).
