For me it's the same as for Rich Heiberger: dots when entering the
password in the minibuffer but then it gets printed in cleartext after
the "Password: " prompt in the *R* buffer.  This is with R version 3.3.1
Patched (2016-09-02 r71210) Platform: x86_64-suse-linux-gnu (64-bit),
ESS 16.04 built today from the Git repository (commit 14e80d60) and with
both a recent Emacs build from the Git master branch as well as Emacs
24.5.
