在Shiny

Question

我有以下Shiny Application：

library(shiny)
library(shinyBS)

UI <- shinyUI(fluidPage(

  fluidRow(
    column(10,
           plotOutput("line_graph")),
    #Pop up windows, for three buttons on the left side
    bsModal("modalExample1", "Your plot", "a_plot", size = "large",
            plotOutput("plot1"), downloadButton('downloadPlot', 'Download')),
    #bsModal("modalExample2", "Your plot", "b_plot", size = "large",
    #        plotOutput("plot2"), downloadButton('downloadPlot', 'Download')),



    column(2,
           actionButton("a_plot","Bubble chart"),
           actionButton("b_plot","Graph view"))
  )
))

Server <- function(input, output) {

  output$line_graph <- renderPlot({hist(10)})
  output$plot1 <- renderPlot({hist(20)})
  output$plot2 <- renderPlot({hist(30)})



}
shinyApp(ui = UI, server = Server)

当我按下按钮＆＃34; a_plot＆＃34;你会得到一个带图表的弹出窗口。这有效。但是我还想要实现这一点，当我按下＆＃34; b_plot＆＃34;时，我会弹出另一个图表。

但是，当我取消注释此代码时：

它不起作用。关于我如何运作的任何反馈意见？

#bsModal("modalExample2", "Your plot", "b_plot", size = "large",
#        plotOutput("plot2"), downloadButton('downloadPlot', 'Download')),

Answer 1

您有2个元素与SELECT developer.developer_name, count(project.dev_id) FROM project JOIN developer ON developer.id = project.dev_id GROUP BY developer.developer_name = id您不能拥有该元素，您需要始终具有唯一downloadPlot

id
