sba*_*bac 16 emacs ess knitr r-markdown
这是对"经典"Rmd文件的改编,我希望使用Emacs(Emacs Speak Statistics)和多态编码将其编织为pdf.我无法找到正确的命令来做到这一点.关于polymode的文档很少.我正在使用社交科学的Emacs入门套件.

You can embed an R code chunk like this:
```{r}
summary(cars)
```
You can also embed plots, for example:
```{r, echo=FALSE}
plot(cars)
```

您可以使用rmarkdown::render()rmarkdown包将文件编织.Rmd为 markdown 并使用单个命令渲染输出文件(PDF、Word、HTML 等)!
我不确定rmarkdownESS 中是否已经包含对工作流程的支持(并且我正在尝试涉足 elisp),因此我编写了一个函数,该函数调用rmarkdown::render()并允许使用rmarkdown::render()前缀 arg(例如C-u)自定义函数调用的输入。
;; spa/rmd-render
;; Global history list allows Emacs to "remember" the last
;; render commands and propose as suggestions in the minibuffer.
(defvar rmd-render-history nil "History list for spa/rmd-render.")
(defun spa/rmd-render (arg)
"Render the current Rmd file to PDF output.
With a prefix arg, edit the R command in the minibuffer"
(interactive "P")
;; Build the default R render command
(setq rcmd (concat "rmarkdown::render('" buffer-file-name "',"
"output_dir = '../reports',"
"output_format = 'pdf_document')"))
;; Check for prefix argument
(if arg
(progn
;; Use last command as the default (if non-nil)
(setq prev-history (car rmd-render-history))
(if prev-history
(setq rcmd prev-history)
nil)
;; Allow the user to modify rcmd
(setq rcmd
(read-from-minibuffer "Run: " rcmd nil nil 'rmd-render-history))
)
;; With no prefix arg, add default rcmd to history
(setq rmd-render-history (add-to-history 'rmd-render-history rcmd)))
;; Build and evaluate the shell command
(setq command (concat "echo \"" rcmd "\" | R --vanilla"))
(compile command))
(define-key polymode-mode-map (kbd "C-c r") 'spa/rmd-render)

请注意,我有一些特定的参数设置,例如output_dir = '../reports'但可以轻松自定义 elisp 以满足您的需求。
C-c r在您的初始化文件中,您只需从文件内部输入.Rmd(或C-u C-c r渲染为不同的格式、位置等)。该命令将打开一个新窗口,其中包含一个名为“错误”的缓冲区*compilation*。
这绝对可以改进,我很想听听建议。
