在服务器上运行R时，如何从emacs ess启动x窗口? [英] How can I launch an x-window from emacs ess when running R on a server?

问题描述

按照ess手册中的说明，我将emacs-snapshot与ssh.el软件包一起使用.

I am using emacs-snapshot with the ssh.el package, following the instructions from the ess manual.

有几种方法可以打开R会话，但这是我的方法:

There are a few ways to open an R session, but this is how I do it:

1. 打开emacs
2. C-x C-f/server:dir/file.R这使我进入ESS [S]模式
3. 输入'plot(1)'
4. 要运行的C-c C-n
5. emacs询问起始目录，然后选择/server:dir/
6. 我想弹出一个数字，但不会.

在shell或流浪汉模式下使用ess-remote时，这也不起作用，但是如果我将起始目录设置为本地桌面，则它确实起作用.

This also doesn't work when using ess-remote in shell or tramp mode, but it does work if I set the starting directory to my local desktop.

任何建议，不胜感激.我当前的解决方法是将文件打印为pdf，然后在DocView模式下打开pdf，但这需要一些额外的步骤并且很慢.

Any advice much appreciated. My current workaround is to print the file to pdf and then open pdf in DocView mode, but this takes a few extra steps and is slow.

推荐答案

我用另一种方法来做:

• ssh -X some.server.com通过x11转发连接到远程服务器.

• ssh -X some.server.com to connect to a remote server with x11 forwarding.

emacsclient -nw重新启动已经运行的Emacs会话

emacsclient -nw to restart an Emacs session that is already running

plot(cumsum(rnorm(100)))

然后，绘图窗口将出现在我ssh离开的初始计算机上.

Then the plot windows appears on the initial machine I ssh'ed away from.

作为注释的后续内容:这适用于任何emacs，无论是emacs还是emacs-snapshot.很长时间以来，我在~/.emacs中使用了(server-start)，但是现在我更喜欢(只是一次)lauch emacs --daemon，之后我可以通过emacsclient(也以emacsclient-snapshot存在)连接.我真的很喜欢-在连接，断开连接和重新连接的持久会话中，它为我提供了R周围的Emacs.

As a follow-up to the comment: This works for any emacs, either emacs or emacs-snapshot. For a long time I used (server-start) in the ~/.emacs but now I prefer that (just once) lauch emacs --daemon after which I can then connect to via emacsclient (which also exists as emacsclient-snapshot). I really like this -- it gives me Emacs around R in a persistent session that I connect, disconnect and reconnect to.
