[英]Suppress automatic figure numbering in pdf output with r markdown/knitr
I am writing a document in R markdown (.rmd). 我正在写一个R markdown(.rmd)的文档。 I would like to be able to knit both Word and PDF outputs.
我希望能够编织Word和PDF输出。 I am having difficulty with figure numbering.
我的图号编号有困难。 With PDF output, the figures were automatically numbered (via Latex output of fig.lp?) But figures were not numbered in Word .
使用PDF输出时,数字会自动编号(通过图.lp的Latex输出?)但数字未在Word中编号。
After much searching, I found code that will provide figure numbering in Word - but now I get double page numbering when knitting a PDF. 经过多次搜索,我发现代码将在Word中提供图形编号 - 但现在我在编织PDF时得到双页编号。 I'm new, so I can't insert an image.
我是新手,所以无法插入图片。 But the figure caption looks like:
但图标题如下:
Figure 1. Figure 1. Blah Blah Blah 图1.图1. Blah Blah Blah
Is there a way to suppress the automatic numbering for PDF? 有没有办法抑制PDF的自动编号?
A similar question was asked here , but a solution was not given. 这里也提出了类似的问题,但没有给出解决方案。 My YAML header and figure numbering chunck are included below.
我的YAML标题和图号编号包含在下面。
YAML: YAML:
output:
pdf_document:
fig_caption: yes
keep_tex: yes
word_document:
fig_caption: yes
Figure numbering code (found via http://galahad.well.ox.ac.uk/repro/ ) 图编号代码(通过http://galahad.well.ox.ac.uk/repro/找到)
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])
}
}
})
this is then called in chunk options as follows: 然后在块选项中调用它,如下所示:
```{r, echo=FALSE, message=FALSE, fig.width=6, fig.cap=figRef("Ex-Airfoil", "Example NACA Airfoil")}

Sure. 当然。 Add a
format
variable for your output format and a handler for that format within figref
. 为输出格式添加
format
变量,并在figref
为该格式添加处理程序。 With RStudio preview edition you could use format <- knitr::opts_knit$get("out.format")
but with the release version you'd need to set it manually. 使用RStudio预览版,您可以使用
format <- knitr::opts_knit$get("out.format")
但是在发布版本中您需要手动设置它。
Then in figref()
add whatever you desire for the output... 然后在
figref()
添加你想要的输出...
if ( format == "latex" ) return( caption )
if (!missing(caption)) {
--- >8 ---
Personally I'd use the preview edition and a switch statement for the handling. 就个人而言,我会使用预览版和switch语句进行处理。 Along the lines of https://stackoverflow.com/a/27321367/173985 .
