如何在Shiny R中保存编辑

Question

I want my end users to be able to update and save comments in a table , through shiny (Action button). If i use the following code , it does open the table, but when i close it , it doesn't save the changes. Here is a sample code:

library(shiny)
library(DT)
library(ggplot2)

shinyApp(
  ui = fluidPage(
    actionButton("Approve", "Click for Approval"),
    tableOutput('edit')
  ),
  server = function(input, output, session) {

    output$edit<- eventReactive(input$Approve, 
    sp.1 <-  edit(mpg))


  }
)

How do i make it save the changes ?

您将需要一个外部文件来存储注释，并在需要时使用Shiny服务器功能进行读写。
