Thanks.  I think you solved this. I used the menu to insert
customization and the working directory now stays same on Ubuntu Linux
Emacs 24.5.1.

 '(inferior-R-args "--no-restore-history --no-save")

The problem is solved.

I also confirmed your (and Vitalie's) other contention. If I move my
init.el file out, then the R wd stays same between R sessions. So that
means I had something that caused the working directory to change to
one directory above.

My init file is a jumble of settings while I try to use various
versions of org mode, python, stata, sas, and who knows what else, I
wonder how do your init file in order? Look at all this crap in here.
There must be some better way than keeping one gigantic laundry bag
full of settings.

Some of these settings are truly necessary, but some are corrections
for old versions of Emacs, or Windows users, or bugs in particular
package versions.

Got advice about how you keep your act together?
