I got a different Macbook Pro, updated it to Yosemite, and I have same
happy result that Vincent found--Emacs found R without a battle.

That means we need to get a config fix on the sick machine.  That's a
little bit encouraging.

Here are some posts from other Mac users about similar problem.

"After an upgrade to Yosemite, R is no longer in PATH:"
http://apple.stackexchange.com/questions/151534/after-an-upgrade-to-yosemite-r-is-no-longer-in-path

Contention is that Yosemite environment has/had PATH twice, and one is
wrong, and depending on which app you use to check the PATH, you get
different answers.

Here's the best explanation I've found: "Getting Yosemite and R to play
nice"

I have a feeling that this is best understood as a PATH or environment
problem, but there is a lot of advice floating about with fixes.

There's an R bug report "OSX 10.10 Yosemite: child processes don't inherit
PATH (which breaks Sys.which)
https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=16042


Resulting in weird advice like this

We verified on that student's computer that the old RStudio failed, but the
new one did find R. RStudio related commentary
