Moralia in Job - dragonslayer


This book grew out of my evergrowing collection of reference materials that was saved as an expanding array of markdown files in a github repo. By assembling it as a book, I hope that it will be more accessible and useful to other R users.


The author would like to acknowledge everyone who has contributed to the books, articles, blog posts, and R packages cited within.

Cover image

The cover image is the historiated initial R from the frontispiece of a 12th-century manuscript of St. Gregory’s Moralia in Job, Dijon, Bibl. Municipale, MS 2. The manuscript was made at the famous reform monastery of Cîteaux in Burgundy around 1111; the frontispiece was added later.

It was downloaded from wikipedia commons; that site notes that the image is in the public domain.

I had initially wanted to use a photo of the Main Hall of the old Cincinnati Library, which one can find all over the internet. But going to the source, I see that it’s not offered by the Public Library of Cincinnati under an open license. But you can follow this link and see it there.
