r语言 - RMarkdown flexdashboard vertical_scroll 不适用于facet_wrap

Question

我希望 flex 仪表板占据全屏(全宽、全高(并滚动以在小平面包装中容纳大量绘图。 使用下面提供的nycflights13使我的问题可重现，并生成不可读的图，超级垂直压缩。 如何在 Flex 仪表板中实现此目的？

```{r dfs and plots, include=FALSE, warning=FALSE, cache=FALSE}
df <- flights %>%
group_by(dest, time_hour) %>%
summarise(n = n()) %>%
ungroup()
sp <- ggplot(df, aes(x=time_hour, y=n)) + geom_line()
fr <- sp + facet_wrap(~ dest)
```
```{r  facet, out.width = '100%', warning=FALSE, echo=FALSE, message=FALSE, error=TRUE}
fr
```

您可以尝试使用fig.height和fig.width选项。这为我提供了相当合理的输出：
