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)))
