R Shiny ui.r参数缺失错误

Question

尝试创建一个ui.r文件，用于绘制具有以下特征的逻辑回归：

选择输入（y变量：细分，x变量：温度，湿度，小时）和可变范围滑块。

我收到以下错误：Error in tag("div", list(...)) : argument is missing, with no default

require(shiny)    
shinyUI(pageWithSidebar(
  headerPanel("Home Automation Data Model - TV"),      
  sidebarPanel(
    wellPanel(
      selectInput(
        inputId = "x_var",
        label = "X variable",
        choices = c(
          "Temperature (Celcius)" = "Temp",
          "Humidity (Percentage)" = "Hum",
          "Hours" = "Hrs"
        ),
        selected = "Temperature"
      ),

      uiOutput("x_range_slider")
    ),      

    wellPanel(
      selectInput(
        inputId = "y_var",
        label = "Y variable",
        choices = c("Breakdowns (Yes/No)" = "y"),
      ),

      uiOutput("y_range_slider")
    ),        

    wellPanel(
      p(strong("Model predictions")),
      checkboxInput(inputId = "mod_logistic",    label = "Logistic (dot-dash)"),
      conditionalPanel(
        condition = "input.mod_loess == true",
        sliderInput(
          inputId = "mod_loess_span",
          label = "Smoothing (alpha)",
          min = 0.15,
          max = 1,
          step = 0.05,
          value = 0.75
        )
      )
    )
  ),

  mainPanel(
    plotOutput(outputId = "main_plot"),        
    conditionalPanel(
      "input.mod_logistic == true",
      p(strong("Logit model")),
      verbatimTextOutput(outputId = "mod_logistic_text")
    ),
  )      
))

  

标记错误（“div”，list（...））：缺少参数，没有默认值

Answer 1

删除ui.R文件中的最后一个逗号。它期待逗号之后的争论。
