[O] :exports not being respected

[Vikas Rawal]

I have a with just the following header, and it is not respecting :exports in 
my R source blocks. The pdf file created has source code as well as the results.

What is wrong? Has the syntax changed again? I have not done anything with 
org-export-babel-evaluate.
