[ESS] Problem getting help window to appear within Emacs

[Munawar Cheema]

I am struggling to figure out why I can't get my help window in an emacs
frame/window.  I have used earlier versions of ESS and R without any
trouble but just came back after a hiatus and embarrassingly can't
figure out this seemingly trivial problem.

I first start emacs -Q
then Eval: (require 'ess-site)
M-x R
After this I then enter a command such as ?ls or help(ls) will pop up a
window in the Window Manager and not in emacs.  How can I get the window
to appear in emacs instead?  I have tried searching for an answer
without luck so I am asking the list.

Thanks in advance
