我在侧边栏面板的 flexdashboard 中添加了一个下载按钮,但是当我编织 .RMD 时它会出现在主面板中。你能指导我如何解决它吗?
这是我正在尝试完成的一个最小示例
---
title: "Download Button in Wrong Panel"
output:
flexdashboard::flex_dashboard:
vertical_layout: scroll
runtime: shiny
---
```{r setup, include=FALSE}
## Setting up required libraries
library(flexdashboard)
library(dplyr)
library(shiny)
library(knitr)
dataset <- read.csv(somefile)
```
Inputs {.sidebar}
-----------------------------------------------------------------------
### Input Filters
```{r input}
## Metric 1
selectInput('metric',
'Choose Metric',
names(dataset %>% select(-default_column)),
selected = "default_metric")
## Download Button
downloadButton('downloadData','Download Result Set')
```
Outputs
-----------------------------------------------------------------------
### List of Customers
```{r output}
subset_dataset <- reactive({
dataset[,c("default_column",input$metric)]
})
renderTable({
subset_dataset()
},
include.rownames = FALSE)
downloadHandler(filename = function() {
paste('resultset-', Sys.Date(), '.csv', sep='')
},
content = function(file) {
write.csv(subset_dataset(), file, row.names = FALSE)
}
)
```

谢谢!
