emacs tramp over an unreliable connection

Question

I want to run R on a remote box under a local Emacs (I do not want to run Emacs on the remote box).

I can run R on a r

Answer 1

Here is an alternative approach using dtach:

(defvar R-remote-host "remote-server")
(defvar R-remote-session "R")
(defvar R-remote-directory "~")
(defun R-remote (&optional remote-host session directory)
  "Connect to the remote-host's dtach session running R."
  (interactive (list
                (read-from-minibuffer "R remote host: " R-remote-host)
                (read-from-minibuffer "R remote session: " R-remote-session)
                (read-from-minibuffer "R remote directory: " R-remote-directory)))
  (pop-to-buffer (make-comint (concat "remote-" session)
                              "ssh" nil "-t" "-t" remote-host
                              "cd" directory ";"
                              "dtach" "-A" (concat ".dtach-" session)
                              "-z" "-E" "-r" "none"
                              inferior-R-program-name "--no-readline"
                              inferior-R-args))
  (ess-remote (process-name (get-buffer-process (current-buffer))) "R")
  (setq comint-process-echoes t))

Call M-x R-remote RET RET RET RET.

It works for me.

PS. The answer to the problem (as opposed to the question as asked) is to use ein with Jupyter.
