鼠标悬停在阴暗而闪亮的位置

我有一些绘图代码可以在RStudio和RPubs上的鼠标悬停时完美地调用数据帧的行名。。。但嵌入到Shiny中时不行。基本代码是：

require(shiny)
require(plotly)
Trial <- read.table("http://history.emory.edu/RAVINA/Aozora/Data/Trial.txt", row.names = 1)
plot_ly(Trial, x=V1, y=V2, text=rownames(Trial), mode = "markers")

但是，“闪亮”版本已完全失效。我想念什么？

require(shiny)
require(plotly)
Trial <- read.table("http://history.emory.edu/RAVINA/Aozora/Data/Trial.txt", row.names = 1)

ui <- fluidPage(
  titlePanel("Word Frequency Analysis for Meiji-era Authors"),
      mainPanel(
      plotOutput("plot"),
      dataTableOutput("Print")
    )
  )


server <- function(input, output){


  output$plot<-renderPlot({
    p <- plot_ly(Trial, x=V1, y=V2, text=rownames(Trial), mode = "text")
    plot(p)
  })
  output$Print<-renderDataTable({Trial})



}

shinyApp(ui = ui, server = server)

您需要将一些基本的闪亮功能替换为它们的对应功能。即plotOutput->plotlyOutput和renderPlot-> renderPlotly。同样，最后一个plot(p)也不是您想要返回的东西：您只想返回p（绘图对象）。

require(shiny)
require(plotly)
Trial <- read.table("http://history.emory.edu/RAVINA/Aozora/Data/Trial.txt", row.names = 1)

ui <- fluidPage(
  titlePanel("Word Frequency Analysis for Meiji-era Authors"),
  mainPanel(
    plotlyOutput("plot"),
    dataTableOutput("Print")
  )
)


server <- function(input, output){            
  output$plot<-renderPlotly({
    p <- plot_ly(Trial, x=V1, y=V2, text=rownames(Trial), mode = "text")
    #plot(p)
    p
  })
  output$Print<-renderDataTable({Trial})     
}

shinyApp(ui = ui, server = server)
