How to evaluate all code blocks when exporting in emacs org-mode

Question

I have an `org-mode` document with many different R source code blocks. Whenever I hit C-c C-e and export to PDF or HTML I get a different prompt asking to evaluate each code block. This wasn't a big deal, but now I have to type `yes` 20+ times. Is there an option to automatically evaluate all the code blocks?

Accepted Answer

I think this is what you want:

```
(setq org-confirm-babel-evaluate nil)
```
