My bibtex references are not outputed

[Rnewuser]

Hello everyone! I have the same issue than last october with a file I try to compile using RStudio: why my biblatex references are not showed up when I knit that file? I get the following warning :

Avis : Package biblatex Warning: Please (re)run Biber on the file:

Avis : (biblatex) Untitled

Avis : (biblatex) and rerun LaTeX afterwards.

How could I fix that? You'll find below my MWE. Where can I insert the following bib entry into this YAML?

@Book{Tufte2006,
author = {Tufte, Edward R.},
title = {The Cognitive Style of PowerPoint : Pitching Out Corrupts Within},
publisher = {Graphics Press LLC},
address = {Cheshire},
year = {2006}, }

Thanks for your help.

@Book{Tufte2006,
author = {Tufte, Edward R.},
title = {The Cognitive Style of PowerPoint : Pitching Out Corrupts Within},
publisher = {Graphics Press LLC},
address = {Cheshire},
year = {2006}, }

I think `year = {2006}, }` should be `year = {2006} }`.

<b>Cancel that.  In bibtex, not biblatex it is fine with or without the comma.</b>

I've just found that I had make a mistake: one of my bib type entry was written original year instead of originalyear or origdate. Now it works.
