ess-smart-equals is disabled by default. In order to enable it, set in your ~/.spacemacs

  (setq-default dotspacemacs-configuration-layers '((ess :variables
                                                         ess-enable-smart-equals t)))

To turn off the automatic replacement of underscores by <-, add the following hook:

  (add-hook 'ess-mode-hook
            (lambda ()
              (ess-toggle-underscore nil)))
