The following function shows the documentation in a new frame. But it also shows the buffer storing the code. How can I show only the documentation, so the documentation fills the whole frame?
(defun qdesc (function)
"Show the documentation for FUNCTION in a new Emacs frame."
(interactive (list (function-called-at-point)))
(let ( (help-frame (make-frame '((name . "Help")
(minibuffer . nil)
(width . 80)
(height . 20)))) )
(with-selected-frame help-frame
(describe-function function))))
Try this:
...
(with-selected-frame help-frame
(switch-to-buffer "*Help*")
(describe-function function)
(delete-other-windows))
...
Untested.

One way you can ensure that your call to describe-function uses the entire frame is by let-binding display-buffer-alist as shown below:
(defun qdesc (function)
"Show the documentation for FUNCTION in a new Emacs frame."
(interactive (list (function-called-at-point)))
(let ((help-frame (make-frame '((name . "Help")
(minibuffer . nil)
(width . 80)
(height . 20))))
(display-buffer-alist '((t display-buffer-full-frame))))
(with-selected-frame help-frame
(describe-function function))))
