That's because the auto-mode-alist tells emacs that .R files should be
in R-mode, so after emacs opens the file, it calls the R-mode function.

That's one way: it's got its downside in that the names have to match,
so you have to remember to modify the auto-mode-alist when you use
different names when tangling.
Another way is to modify the function below:

to call R-mode explicitly. That's got its own downside: all your
tangled files are going to be in R-mode.
The point is that you have to tell emacs somehow what you are doing:
it can't guess that you are producing R-mode files without some help.
