I am trying to write an Elisp function that will create a new frame and in that new frame open two files split vertically.
I have been unable to find anything about this in the Elisp manual, node Creating Frames
How can I do this?

You can try this function:
(defun my/open-files-vert-in-new-frame (file1 file2) (interactive "f\nf") (select-frame-set-input-focus (make-frame)) (find-file file1) (split-window-below) (find-file file2))
The key is
select-frame-set-input-focus which makes subsequent functions operating on windows of the new frame and set input focus on it.
