如何使用动态创建的选项卡和 for 循环显示 ggplotly 图？

Question

我有 R markdown 文档，我想动态创建带有 ggplotly 图形的选项卡

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

```{r}
library(ggplot2)
library(plotly)
```

```{r}
fig=ggplot(cars)+geom_point(aes(speed, dist))
```

# level 1
## level 2{.tabset .tabset-pills}

```{r echo=FALSE, results='asis'}

for (h in 1:3){
  cat("###", h,'{-}',  '\n\n')
 ggplotly(fig)
  cat( '\n\n')
}
```

我知道它与普通的 ggplot 图表不同，我在这里查看了解决方案：enter link description here 但它对我不起作用

Answer 1

按照post，可以这样实现：

编辑：在post 之后，我添加了两个函数来将fig.width 和fig.height 传递给ggplotly。

编辑2：添加了额外使用plotly::subplots的代码。

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

```{r}
library(ggplot2)
library(plotly)
```

```{r, echo=FALSE}
# Get the current figure size in pixels:
get_w <- function() {
  with(knitr::opts_current$get(c("fig.width", "dpi", "fig.retina")),
       fig.width*dpi/fig.retina)
}

get_h <- function() {
  with(knitr::opts_current$get(c("fig.height", "dpi", "fig.retina")),
       fig.height*dpi/fig.retina)
}
```

```{r}
fig <- ggplot(cars) + 
  geom_point(aes(speed, dist))
```

# level 1

## level 2 {.tabset .tabset-pills}

```{r, include=FALSE}
htmltools::tagList(ggplotly(fig))
```

```{r echo=FALSE, results='asis', fig.width=4, fig.height=4}
fig <- ggplotly(fig, width = get_w(), height = get_h())
for (h in 1:3) {
  cat("###", h, '{-}',  '\n\n')
  print(htmltools::tagList(plotly::subplot(fig, fig, nrows=2, heights = c(0.1, 0.9))))
  cat( '\n\n')
}
```

也从this link 找到了解决方案，这不需要 HTML，只需要 markdown。

 ```{r setup, include=FALSE}
 knitr::opts_chunk$set(echo = TRUE)
 ```

 ```{r}
 library(ggplot2)
 library(plotly)
 ```

 ```{r}
 fig <- ggplot(cars) + 
   geom_point(aes(speed, dist))
 ```

 ## Results {.tabset}

 ### 1

 We show a scatter plot in this section.

 ```{r}
 ggplotly(fig)
 ```

 ### 2

 We show the data in this tab.

 ```{r}
 ggplotly(fig)
 ```
