A preprint of a new handbook titled R for Photobiology is now available. Only a few pages are based on Beyond the Visible, the handbook produced during COST Action FA0906 UV4growth. Everything else is new material. As authors we have decided to publish it before it is finished, so that we can make changes and additions based on your comments. It is available through Leanpub. For dowloading the PDF, whether you decide to pay for it or not, you will have to register as user of the Leanpub the site. You will only receive an occasional message from the authors of the book you have downloaded when a significant update to the books become available. And you will be able to opt-out from receiving them.
Hoping that you will find the handbook useful, and looking forward to your suggestions for improvements!
