Thank you Stephen. The following works for me.

(setq ess-ask-for-ess-directory nil)
(setq ess-directory "~/")

Actually I have done some RTFM and found section "3.5 Changing the
startup actions", where this is described but I had problems since
manual says

"If you do not wish ESS to prompt for a starting directory when starting
a new process, set the variable `ess-ask-for-ess-directory' to `nil'.
In this case, the value of the variable `ess-directory' is used as the
starting directory.  The default value for this variable is your home

However, when I set the variable `ess-ask-for-ess-directory' to `nil' R
session starts in directory of last visited file. Say I have opened file
from "/some/where/on/my/disk" and when I fire M-x R, R starts in
"/some/where/on/my/disk" and not from my home directory. Did I do
anything wrong or is my reading of manual bad. However, as already noted
above manual setting of `ess-directory' variable solves this problem.
Perhaps manual should be modified according to this?

Thank you very much for providing such a great interface!
