是否有一种方法可以使用ggiraph和onclick在R Shiny的Modal窗口中显示已过滤的数据表?

问题描述 投票:0回答:1

[我想使用ggiraph进行交互式绘图,在其中我的onclick会启动一个模态,这是一个弹出窗口,显示与我单击的单个数据点有关的信息。

下面是我的代码。我无法使模式弹出窗口正常工作。我可以弹出一个Modal弹出窗口,但是它是空白的。但是,我可以使用此处提供的示例来使表格进行自我过滤。

https://davidgohel.github.io/ggiraph/articles/offcran/shiny.html

'run_girafe_example(“ DT”)'

我希望此过滤后的表格显示在模式弹出窗口中。可能以更好的格式转置和呈现数据。但是,如果我可以在模态中显示数据,则可以弄清楚以后如何表示它。我只需要弄清楚如何让Modal首先显示过滤后的数据表即可!

任何帮助将不胜感激:)

您需要在DT::renderDataTable通话中拨打modalDialog

library(ggiraph)
library(ggplot2)
library(tidyverse)
library(htmltools)
library(DT)
library(shinyBS)
library(shinydashboard)

theme_set(theme_minimal())

data <- mtcars

ui <- fluidPage(

  fluidRow(
    column(width=12,
           h4("click a point, the data table will be filtered...")
    )
  ),

  fluidRow(
    column(width=12,
           ggiraphOutput("fixedplot")
    )
  )
  ,

  fluidRow(
    column(width=12,
           includeScript(path = "set_search_val.js"),
           DT::dataTableOutput("modaltable")
    )
  )
)

server <- function(input, output, session) {

  output$fixedplot <-renderGirafe({
    data$label <- gsub(pattern = "'", " ", row.names(data) )
    data$onclick <- paste0("set_search_val(\"", data$label, "\");")

    gg <- ggplot(data = data,
                 mapping = aes(x=wt, y=mpg,
                               tooltip = label,
                               data_id = label, 
                               onclick = onclick 
                 ) 
    ) +
      geom_point_interactive()

    girafe(code = print (gg), 
           options = list(
             opts_selection(type = "single")
           )
    )
  })

  observeEvent(input$fixedplot_selected,{
    showModal(modalDialog(
      tags$caption("Table"),
      DT::renderDataTable({
        car_data <- data[,1:7]
        DT::datatable(car_data, escape = FALSE)
      })
    ))
  }
  )

  output$modaltable <- DT::renderDataTable({
    car_data <- data[,1:7]
    DT::datatable(car_data, escape = FALSE)
  })
}

shinyApp(ui = ui, server = server)
