在rmarkdown :: beamer_presentation中将多个框架选项传递到单个框架 [英] Passing multiple frame options to a single frame in an rmarkdown::beamer_presentation

问题描述

如何在 rmarkdown :: beamer_presentation 中将多个帧选项传递到特定帧?

How to pass several frame options to a specific frame in an rmarkdown::beamer_presentation?

在下面的MWE中，第二帧应该包含与前一帧相同的表，只是多几行.

In the MWE below, the second frame should contain the same table as on the frame before, just with a few more rows.

因此

1. 理想情况下，两个框架的页面编号都是相同的(=> {.noframenumbering} )

为简单地将第2帧上的行添加到第1帧下的行，两个帧的内容应在顶部对齐(=> {.t} ).由于其他一些幻灯片需要框架内容的垂直居中对齐，因此不希望在YAML标头中设置 classoption:t .

to simply add the rows on frame 2 below those on frame 1, the content of both frame should be top-aligned (=> {.t}). Since some other slides require vertical center alignment of frame content, setting classoption: t in the YAML header would be undesired.

MWE

output:
  bookdown::pdf_book:
    base_format: rmarkdown::beamer_presentation
    slide_level: 2
    keep_tex: true
---

## Slide

```{r table, cars, echo = FALSE}
library(kableExtra)
knitr::kable(head(mtcars[1:3, 1:3]), caption = "Table caption")
```

## Slide {.noframenumbering}

```{r table, cars2, echo = FALSE}
library(kableExtra)
knitr::kable(head(mtcars[1:6, 1:3]), caption = "Table caption")
```

(在YAML标头中添加多个类选项是可行的，可以使用逗号将它们分开，例如 classoption:t，Aspectratio = 169 .对于我来说，使用相同的方法无法将它们调整为单帧，即 ##幻灯片{.noframenumbering，.t} .)

(adding multiple classoptions in the YAML-header is feasible by separating them with a comma, e.g. classoption: t, aspectratio=169. The same approach did not work for me in adjusting them for a single frame though, i.e., ## Slide {.noframenumbering,.t}.)

推荐答案

您可以使用以下语法将多个选项传递给框架:

You can use the following syntax to pass multiple options to a frame:

---
output:
  bookdown::pdf_book:
    base_format: rmarkdown::beamer_presentation
    slide_level: 2
    keep_tex: true
---

## Slide {.t}

```{r table, cars, echo = FALSE}
library(kableExtra)
knitr::kable(head(mtcars[1:3, 1:3]), caption = "Table caption")
```

## Slide {.noframenumbering .t}

```{r table, cars2, echo = FALSE}
library(kableExtra)
knitr::kable(head(mtcars[1:6, 1:3]), caption = "Table caption")
```
