The plot and shiny mouse

Question

I have some kind of intricate code that perfectly names the row names for the data frame when you hover both inside RStudio and RPubs., But not when they are built into Shiny. Main code:

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") 

The brilliant version, however, is completely dead. What am I missing?

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)

Answer 1

You need to change some basic brilliant functions for your interlocutors. Namely plotOutput→ plotlyOutputand renderPlot→ renderPlotly. Also, the latter is plot(p)not what you want to return: you just want to return p(plot object).

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)
