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:"

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

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)

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
