Not that I am aware of.  Usually, the behaviour will be controlled by
some variable.  For instance, in org, when asking for an agenda view
(org-agenda), the following variable controls what it does in terms of
frames and windows within frames:

,----[ C-h v org-agenda-window-setup RET ]
| org-agenda-window-setup is a variable defined in `org-agenda.el'.
| Its value is current-window
| Original value was reorganize-frame
| 
| Documentation:
| How the agenda buffer should be displayed.
| Possible values for this option are:
| 
| current-window    Show agenda in the current window, keeping all other windows.
| other-window      Use `switch-to-buffer-other-window' to display agenda.
| only-window       Show agenda, deleting all other windows.
| reorganize-frame  Show only two windows on the current frame, the current
|                   window and the agenda.
| other-frame       Use `switch-to-buffer-other-frame' to display agenda.
|                   Also, when exiting the agenda, kill that frame.
| See also the variable `org-agenda-restore-windows-after-quit'.
| 
| You can customize this variable.

Usually, these variables are described in the info manuals.
