在R中缩放flexdashboard gauge

Question

我正在尝试使用flexdashboard::gauge,但它总是相同的大小(不缩放),我不知道如何改变它的大小.我知道有一种方法可以使用renderPlot和设置例如正常情节height.有没有办法做类似的事情renderGauge？

这是我的代码:

---
title: "Test"
output: 
  flexdashboard::flex_dashboard:
    orientation: columns
    vertical_layout: fill
runtime: shiny    
---



```{r setup, include=FALSE}
library(flexdashboard)
library(shiny)
library(googleVis)
```


Column {.sidebar}
-----------------------------------------------------------------------

```{r}
selectInput("n", label = "Number of bins:",
            choices = c(10, 20, 35, 50), selected = 20)
```



Column {data-width=500}
-----------------------------------------------------------------------


### Gauge

```{r}
renderGauge({
    invalidateLater(1000, session)
    dane <- round(runif(1,0,100))
    df <- data.frame(Label = "IRR", Value = as.numeric(dane))
    gauge(dane, min = 0, max = 100, symbol = '%', gaugeSectors(
  success = c(80, 100), warning = c(40, 79), danger = c(0, 39)
))
  })

```

### Chart A

```{r }
renderPlot({
  plot(1:10,1:10)
})
```


Column {data-width=500}
-----------------------------------------------------------------------

### Chart B

```{r}
renderPlot({
  plot(1:10,1:10)
})
```

### Chart C

```{r}
renderPlot({
  plot(1:10,1:10)
})
```

其余图表将填补这个空缺.你知道如何让这个规格更大吗？谢谢!

毕竟这可能并不太难。真正的问题似乎在于justgage.css，它将高度固定为 160px。您可以通过添加自定义 css 来覆盖它，例如通过以下方式：

文件extra.css：

.html-widget.gauge {
  height: 100%; /*or try sth like 320px instead of 100%, whatever you prefer*/
}

.html-widget.gauge svg {
  height: 100%; /*or try sth like 320px instead of 100%, whatever you prefer*/
  margin-top: -10px;
  margin-bottom: -40px;
}

然后编辑文档的yaml 标头，如下所示：

---
title: "Test"
output: 
  flexdashboard::flex_dashboard:
    orientation: columns
    vertical_layout: fill
    css: extra.css
runtime: shiny
---

这期望该文件extra.css与主文档位于同一目录中。
