Jabref is used to produce a searchable version of R.bib.

We use a slight modification (to make the W3C validator happy) of the
built in export filter 'tablerefsabsbib', which is available at

[https://github.com/JabRef/jabref/tree/master/src/main/resources/resource/layout/tablerefsabsbib]

Basically, we change the explicit widths in 
<thead><tr><th width="20%">Author</th><th width="30%">Title</th>...
to
<thead><tr><th style="width:20%">Author</th><th style="width:30%">Title</th>...

Our modified filter is in the `jabref-custom` directory.  Before it
can be used, it has to be registered with jabref through the GUI.
Here are the steps needed to do so, taken from
[http://jabref.sourceforge.net/help/CustomExports.php]

 - The only requirement for a valid export filter is the existence of
   a file with the extension .layout. To add a new custom export
   filter, open the dialog box Options -> Manage custom exports, and
   click Add new. A new dialog box will appear, allowing you to
   specify a name for the export filter (which will appear as one of
   the choices in the File type dropdown menu of the file dialog when
   you use the File -> Export menu choice in the JabRef window), the
   path to the .layout file, and the preferred file extension for the
   export filter (which will be the suggested extension in the file
   dialog when you use the export filter).

Fill in the dialog box with values

- jr
- /path/to/R-project-web/trunk/doc/bib/jabref-custom/jr.layout
- html


Run

`jabref`

and then
