“:results silent” just means “silent except for the minibuffer”; IDK

Yes, that’s what I meant (and didn’t explain well).  Org writes R’s
output to a file, and then imports it into Emacs (to print in the
minibuffer).  But it also does an expensive transformation before
printing it – whence the slowdown.

I agree that this is sub-optimal.

I seem to remember that ob-R.el is unmaintained (or was at some point in
the past).  Once there is consensus on what a fix should look like, I
can attempt to produce a patch implementing it.  And I’ll take a crack
at error reporting in the minibuffer too.
