如何使用动态创建的选项卡和 for 循环显示 ggplotly 绘图？

我有 R markdown 文档，我想动态创建其中包含 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')
}
```

我明白这与正常情况不同ggplot图表，我在这里查看了解决方案：在此输入链接描述 https://github.com/ropensci/plotly/issues/570但这对我不起作用

按照此post https://github.com/ropensci/plotly/issues/273#issuecomment-531254687这可以像这样实现：

Edit:按照此post https://stackoverflow.com/questions/42532129/passing-fig-width-into-a-taglist我添加了两个函数来传递fig.width and fig.height到 ggplotly。

Edit 2:添加了额外使用的代码plotly::subplots.

```{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')
}
```
