WinXP emacs 上远程 R 的双重提示和乱码 R 帮助
我已经从 Vincent Goulet 安装了一个修改版 Emacs 版本(来自 Vincent Goulet),并且我想使用 ess-remote 运行和编辑远程 Unix 服务器上包含的 R 脚本。经过大量搜索后,我能够通过以下方式连接到远程 R 会话:
- 使用 Mx shell 打开 shell 提示符,
- 输入以下命令:plink -X -C username@server
- ,我使用一个简单的命令在 shell 中启动 R
R
- 使用命令
Mx ess-remote
将其指定为远程进程
输入密码后 为了成功地与 R 交互,我总是得到双重提示,更糟糕的是,如果打开函数的帮助文件,我会在同一个 R 进程缓冲区中得到乱码文本,而不是打开带有清晰 R 帮助文本的新缓冲区。如何获得帮助缓冲区以在单独的窗口中打开,就像通常的 emacs 和 R 交互一样,以及如何在执行 shell 时摆脱双提示?

Arithmetic Mean
Description:
Generic function for the (trimmed) arithmetic mean.
Usage:
mean(x, ...)
## Default S3 method:
mean(x, trim = 0, na.rm = FALSE, ...)
Arguments:
x: An R object. Currently there are methods for numeric/logical
vectors and date, date-time and time interval objects, and
for data frames all of whose columns have a method. Complex
vectors are allowed for 'trim = 0', only.
trim: the fraction (0 to 0.5) of observations to be trimmed from
[24;1H[K:[24;1H[24;1H[K] 计算平均值之前“x”的每一端。修剪值 [24;1H[K: [24;1H[24;1H[K 超出该范围被视为最近的端点。
na.rm: a logical value indicating whether 'NA' values should be
stripped before the computation proceeds.
...: further arguments passed to or from other methods.
Value:
For a data frame, a named vector with the appropriate method being
applied column by column.
If 'trim' is zero (the default), the arithmetic mean of the values
in 'x' is computed, as a numeric or complex vector of length one.
If 'x' is not logical (coerced to numeric), numeric (including
integer) or complex, 'NA_real_' is returned, with a warning.
If 'trim' is non-zero, a symmetrically trimmed mean is computed
with a fraction of 'trim' observations deleted from each end
before the mean is computed.

I have installed a modified Emacs version for Windows XP from Vincent Goulet and I want to run and edit R scripts contained on a remote Unix server using ess-remote. After a lot of searching I am able to connect to a remote R session in the following way:
- Open a shell prompt with
M-x shell
- enter the following command:
plink -X -C username@server
- After entering password, I start up R in the shell with a simple command
R
- Assign this as a remote process with command
M-x ess-remote
While I am able to interact with R successfully, I always get a double prompt and worse yet, if open a help file for a function, I get garbled text in the same R process buffer, instead of a new buffer opening with legible R help text. How can I get any help buffer to open in a separate window like the usual emacs and R interaction, and how can I get rid of the double-prompts when I execute the shell?

对于颜色代码问题,您需要在 shell 模式下启用 ansi-color 支持:
我在示例中没有看到双提示,但您可以创建一个自定义 shell autoexec 文件来设置自定义提示:
(编辑:啊,你的意思是 R 中的双重

提示。我不知道这一点,抱歉,我会在下面留下评论,以防它对某人有用......)例如,
init_bash.sh
可能包含export PS1="\n\u@\h \w $ "
用于简单的无色提示。请参阅 Ch f shell RET 了解更多信息。
For the colour code issue, you need to enable ansi-color support in shell mode:
I'm not seeing the double-prompt in your examples, but you can create a custom shell autoexec file to set a custom prompt:
(edit: Ah, you meant a double

prompt within R. I don't know about that, sorry. I'll leave the comments below in case it's useful to someone...)e.g.
init_bash.sh
might containexport PS1="\n\u@\h \w $ "
for a simple uncoloured prompt.See C-h f shell RET for more information.
