Emacs ESS：R REPL 的管道输出到缓冲区

Question

我希望能够在 R 的 REPL 上执行语句，并可以选择将其通过管道传输到缓冲区，以便我稍后可以快速参考它。

到运行一个 shell 命令并输出到 *shell command buffer* 我可以按照 this question 使用 M-!。如果不求助于 write.csv()，R 的 REPL 的等价物是什么？

您可以使用 ess-inf 中的 ess-command 将输出重定向到另一个缓冲区。示例如下所示，

(defun redirect-ess-output (command &optional buffer process)
  (interactive (list (read-from-minibuffer "Command: ")))
  (let ((buff (get-buffer-create (or buffer "*r-output*")))
        ;; 'ess-get-process' defaults to process local to current
        ;; buffer, so to call from anywhere default to "R"
        (proc (ess-get-process (or process "R"))))
    ;; send a trailing newline to process
    (unless (string-match-p "\n$" command)
      (setq command (concat command "\n")))
    (ess-command command buff 'sleep nil nil proc)
    (with-current-buffer buff
      ;; process stuff
      (pop-to-buffer buff))))
