r - ess-dired : I get this error "no ESS process is associated with this buffer now"

Question

使用 ess-rdired为了浏览对象，我遵循 ESS 手册并将以下内容添加到我的 .emacs :

(autoload 'ess-rdired "ess-rdired"
  "View *R* objects in a dired-like buffer." t)

当我做 M-x ess-rdired ，会出现一个缓冲区，列出当前环境中的对象。

但是，当我按下像 p, v 这样的快捷方式时，我收到了这个错误:

"no ESS process is associated with this buffer now."

此外，可以 ess-rdired更改对象时更新对象的信息？

我有同样的问题，果然 C-c C-s 解决了它。我将以下函数添加到我的 dot emacs 文件中以自动执行此操作。我将该函数映射到 C-c o，它将加载 rdired 或刷新它。任何改进将非常受欢迎!

(defun ess-R-show-objects ()
  "Calls rdired and associates with R process"
  (interactive)
  (if (get-buffer "*R*") ;;Only run if R is running
      (progn
        (ess-rdired)
        (ess-rdired-switch-process))
    (message "No R process")
    )
  )
(global-set-key (kbd "\C-co") 'ess-R-show-objects)
