Suggestions on 3.7.1 compile function section #222

Closed hxd1011 closed 7 years ago

It seems to me that R 3.4 comes with JIT compiler. And the demo (fig. 3.4) can not be replicated in current R.

Thanks for reporting this. More Colin's side of things than mine so look forward to see what he has to say on the matter.

@hxd1011 You're correct; 3.4.0 has the JIT compiler switched on by default (but not for additional packages). In the printed version of the book, we managed to sneak a footnote in the week before the was published (I monitor the R-Core commits).

I don't think I want to change the online version with a drastic change, e.g. removing the section. However, I'll add a note to say that this is for 3.3 and below.

Thanks
