Question

您好我有一个简单的闪亮应用程序，根据列＃34; OriginId＆＃34;创建一个饼图。我的数据框架。问题是，当我使用text = ~paste( table(testdata$OriginId), ' clients')时，我希望鼠标悬停为我提供确切数量的客户端。但不是这个我犯了一个错误。 Column {文本{1}}。这是我的代码：

must be length 1 or 4, not 2

Answer 1

我不确定是否可能，但与此同时，这是另一种选择。

testdata <- data.frame(testdata %>% group_by(OriginId) %>% mutate(Counts = n())) 

##Add a new Counts (what the table do) column and use this column for your hover text.

## ui.R ##
library(shinydashboard)
library(plotly)

dashboardPage(
  dashboardHeader(),
  dashboardSidebar(),
  dashboardBody()
)

library(shinydashboard)

ui <- dashboardPage(
  dashboardHeader(title = "Basic dashboard"),

  ## Sidebar content
  dashboardSidebar(
    sidebarMenu(
      menuItem("Dashboard", tabName = "dashboard", icon = icon("dashboard"))
    )
  ),

  ## Body content
  dashboardBody(
    tabItems(
      # First tab content
      tabItem(tabName = "dashboard",
              fluidRow(
                box(
                  plotlyOutput("pie",height = 250))



              )

      )

      # Second tab content


    )
  )
)
#server.r
server <- function(input, output) {


  output$pie<-renderPlotly({
    p <- plot_ly(testdata, labels = ~OriginId, values = table(testdata$OriginId), type = 'pie',
                 textposition = 'inside',
                 textinfo = 'label+percent',
                 insidetextfont = list(color = '#FFFFFF'),
                 hoverinfo = 'text',
                 text = ~paste(testdata$Counts, ' clients'),
                 marker = list(
                   line = list(color = '#FFFFFF', width = 1)),
                 #The 'pull' attribute can also be used to create space between the sectors
                 showlegend = FALSE) %>%
      layout(title = 'Domestic vs International Share',
             xaxis = list(showgrid = FALSE, zeroline = FALSE, showticklabels = FALSE),
             yaxis = list(showgrid = FALSE, zeroline = FALSE, showticklabels = FALSE))
  })

}

shinyApp(ui, server)
