\@ref()
表示法不能与投影仪表示一起使用?以下问题可能会在编织PDF文档时提醒您一些有关交叉引用的问题,例如this,但是答案中介绍的方法在进行投影仪演示时没有帮助。
现在,我感到困惑,因为当我用选项\@ref(fig:label-to-refer-figure)
编织\@ref(tab:label-to-refer-table)
文件时,.Rmd
和output: beamer_presentation
表示法引用图形/表格的方法不起作用。如下图所示,交叉引用的原始代码出现在输出的PDF文件中,我无法参考图形/表格编号。尽管即使在列出的环境以及纯文本字段中引用都很好,但是对图形/表格编号的交叉引用并未正确生效。
我在此处发布的MWE来自以下来源:test-beamer.Rmd
和myref.bib
。

```{r setup, include=FALSE}

## The only thing
With Table \@ref(tab:under-pressure-table), @test-master shows that Figure \@ref(fig:under-pressure) depicts...
## Slide with Bullets in which I want to refer a figure
- \@ref(fig:under-pressure)
- @test-master
- \@ref(tab:under-pressure-table)
## Slide with R Output
```{r cars, echo = TRUE}
summary(cars)
```
## Slide with Plot
```{r under-pressure, fig.cap='Under Pressure', fig.pos='h', out.width="0.75\\textwidth"}
plot(pressure)
```
## Slide with Table
```{r under-pressure-table, caption = "This is a table"}
knitr::kable(pressure)
```
## More extraordinary
With Table \@ref(tab:under-pressure-table), @test-master shows that Figure \@ref(fig:under-pressure) depicts...
编辑:我在图形块中添加了fig.cap='Under Pressure', fig.pos='h', out.width="0.75\\textwidth"
,并在caption = "This is a table"
中添加了knitr::kable()
。没有这些代码,标题和表格/数字都根本不会出现...但是,即使将它们提供给整个.Rmd
文件,问题仍然存在,除非您执行@Yihui的回答。
myref.bib
@master{test-master,
author = {Freddie Mercury and Brian May and John Deacon and Roger Taylor},
title = {Bohemian {R}hapsody: {W}e are the champions},
school = {{Queen}},

address = {London}
}

\@ref()
表示法仅是 bookdown 的功能。要将此功能移植到一般的R Markdown文档中,您可以设置特定 bookdown 输出格式(例如
base_format
选项
output:
bookdown::pdf_book:
base_format: rmarkdown::beamer_presentation
有关详细信息,请参见Section 3.4 of the bookdown book。
适合该问题的MWE的已完成yaml部分可能是这样的:
