Quarto not rendering figures properly inside a conditional statement

问题

我正在使用 quarto 创建一个 HTML 文档。我想要有一些并排的图表。

当我尝试在条件语句内部呈现并排的图表时，quarto 只呈现第二个图表。下面是一个可重现的示例。

title: "RenderTest"
format: html

  1. library(tidyverse)

直接的图表 - 无条件

  1. #| layout-ncol: 2
  2. #| out-width: "50%"
  4. ggplot(mtcars, aes(x = mpg, y = wt)) + geom_point()
  5. ggplot(mtcars, aes(x = hp, y = disp)) + geom_point()

现在加入条件：

  1. #| layout-ncol: 2
  2. #| out-width: "50%"
  4. test <- F
  6. if(test){
  7.   ggplot(mtcars, aes(x = mpg, y = wt)) + geom_point()
  8. } else {
  9.   ggplot(mtcars, aes(x = mpg, y = wt)) + geom_point()
  10.   ggplot(mtcars, aes(x = hp, y = disp)) + geom_point()
  11. }

这会产生以下输出：

Quarto在条件语句内部未正确呈现图表。

你可以看到，在条件语句内部，只有第二个图表被显示出来。我很困惑。这是一个 bug 吗？还是有一些基本的东西我不理解？

英文:

I am using quarto to create an html document. I want to have some side-by-side plots.

When I try to render side-by-side plots from inside of a conditional statement, quarto only renders the second plot. Below is a reproducible example.

  1. ---
  2. title: &quot;RenderTest&quot;
  3. format: html
  4. ---
  1. library(tidyverse)

Straight-up plot - No Conditional

  1. #| layout-ncol: 2
  2. #| out-width: &quot;50%&quot;
  4. ggplot(mtcars, aes(x = mpg, y = wt)) + geom_point()
  5. ggplot(mtcars, aes(x = hp, y = disp)) + geom_point()

Now with conditional:

  1. #| layout-ncol: 2
  2. #| out-width: &quot;50%&quot;
  4. test &lt;- F
  6. if(test){
  7.   ggplot(mtcars, aes(x = mpg, y = wt)) + geom_point()
  8. } else {
  9.   ggplot(mtcars, aes(x = mpg, y = wt)) + geom_point()
  10.   ggplot(mtcars, aes(x = hp, y = disp)) + geom_point()
  11. }

This produces the following output:

Quarto在条件语句内部未正确呈现图表。

You can see that inside the conditional, only the second plot gets displayed. I'm very confused. Is this a bug? Is there something fundamental I don't understand?

  1. 你应该像这样“打印”ggplot调用：
  3.     ---
  4.     title: "RenderTest"
  5.     format: html
  6.     ---
  7.     
  8.     ```{r}
  9.     library(tidyverse)
  10.     ```
  11.     
  12.     ```{r}
  13.     #| layout-ncol: 2
  14.     #| out-width: "50%"
  15.     
  16.     test <- FALSE
  17.     
  18.     if(test){
  19.       ggplot(mtcars, aes(x = mpg, y = wt)) + geom_point()
  20.     } else {
  21.       print(ggplot(mtcars, aes(x = mpg, y = wt)) + geom_point())
  22.       print(ggplot(mtcars, aes(x = hp, y = disp)) + geom_point())
  23.     }
  24.     ```
  26. 输出：

You should print the ggplot calls like this:

  1. ---
  2. title: &quot;RenderTest&quot;
  3. format: html
  4. ---
  6. ```{r}
  7. library(tidyverse)
  8. ```
  10. ```{r}
  11. #| layout-ncol: 2
  12. #| out-width: &quot;50%&quot;
  14. test &lt;- FALSE
  16. if(test){
  17.   ggplot(mtcars, aes(x = mpg, y = wt)) + geom_point()
  18. } else {
  19.   print(ggplot(mtcars, aes(x = mpg, y = wt)) + geom_point())
  20.   print(ggplot(mtcars, aes(x = hp, y = disp)) + geom_point())
  21. }
  22. ```

Output:

Quarto在条件语句内部未正确呈现图表。
