使用R markdown/knitr抑制pdf输出中的自动图形编号 [英] Suppress automatic figure numbering in pdf output with r markdown/knitr

问题描述

我正在用R markdown(.rmd)编写文档.我希望能够同时编织Word和PDF输出.我在数字编号方面遇到困难.使用PDF输出时，数字会自动编号(通过fig.lp的Latex输出?)，但是数字未在Word中编号.

I am writing a document in R markdown (.rmd). I would like to be able to knit both Word and PDF outputs. I am having difficulty with figure numbering. With PDF output, the figures were automatically numbered (via Latex output of fig.lp?) But figures were not numbered in Word .

经过大量搜索，我找到了可以在Word中提供图形编号的代码-但是现在，在编织PDF时获得了双页编号.我是新手，所以我无法插入图片.但是图形标题看起来像:

After much searching, I found code that will provide figure numbering in Word - but now I get double page numbering when knitting a PDF. I'm new, so I can't insert an image. But the figure caption looks like:

图1.图1. Blah Blah Blah

Figure 1. Figure 1. Blah Blah Blah

是否可以禁止对PDF进行自动编号?

有人问了类似的问题

A similar question was asked here, but a solution was not given. My YAML header and figure numbering chunck are included below.

YAML:

output:
  pdf_document:
    fig_caption: yes
    keep_tex: yes
  word_document:
    fig_caption: yes

图形编号代码(可通过 http://galahad.well.ox.ac找到. uk/repro/)

Figure numbering code (found via http://galahad.well.ox.ac.uk/repro/)

figRef <- local({
    tag <- numeric()
    created <- logical()
    used <- logical()
    function(label, caption, prefix = options("figcap.prefix"), 
        sep = options("figcap.sep"), prefix.highlight = options("figcap.prefix.highlight")) {
        i <- which(names(tag) == label)
        if (length(i) == 0) {
            i <- length(tag) + 1
            tag <<- c(tag, i)
            names(tag)[length(tag)] <<- label
            used <<- c(used, FALSE)
            names(used)[length(used)] <<- label
            created <<- c(created, FALSE)
            names(created)[length(created)] <<- label
        }
        if (!missing(caption)) {
            created[label] <<- TRUE
            paste0(prefix.highlight, prefix, " ", i, sep, prefix.highlight, 
                " ", caption)
        } else {
            used[label] <<- TRUE
            paste(prefix, tag[label])
        }
    }
})

然后在块选项中按如下所示调用它:

this is then called in chunk options as follows:

```{r, echo=FALSE, message=FALSE, fig.width=6, fig.cap=figRef("Ex-Airfoil", "Example NACA Airfoil")}

好的.为您的输出格式添加一个format变量，并在figref中为该格式添加一个处理程序.使用RStudio预览版，您可以使用format <- knitr::opts_knit$get("out.format")，但是对于发行版，则需要手动进行设置.
然后在figref()中添加所需的输出...

Sure. Add a format variable for your output format and a handler for that format within figref. With RStudio preview edition you could use format <- knitr::opts_knit$get("out.format") but with the release version you'd need to set it manually.
Then in figref() add whatever you desire for the output...

    if ( format == "latex" ) return( caption )
    if (!missing(caption)) {
    --- >8 ---

我个人将使用预览版和switch语句进行处理.遵循 https://stackoverflow.com/a/27321367/173985 .

Personally I'd use the preview edition and a switch statement for the handling. Along the lines of https://stackoverflow.com/a/27321367/173985.
