整个内容太大，无法发布，但这应该足够了

我的ui.R文件包含

library(shiny)


data <- read.csv("Amstat.csv", header = TRUE)
modelTypes <- unique(data$Model)

# Define UI for application that draws a histogram
shinyUI(fluidPage(

  # Application title
  titlePanel("Car prices"),

  # Sidebar with a slider input for number of bins 
  sidebarLayout(
    sidebarPanel(
      selectInput("Model", 
                  label = "Choose a Model to display",
                  choices = modelTypes),

      selectInput("price",
                  label = "Choose a price",
                  choices = list("Left","Center", "Right"),
                  selected="CENTER")


    ),

    # Show a plot of the generated distribution
    mainPanel(
       plotOutput("carpricePlot")
    )
  )
))

库（闪亮）
数据当您使用UI中的变量（
input$…
）时，您必须以反应式的方式执行此操作：

shinyServer(function(input, output) {

  data <- read.csv("Amstat.csv", header = TRUE)
  amstat1<-reactive({
    data %>% select(Type,Price,Model ) %>% filter(Model == input$Model)
    })

  output$carpricePlot <- renderPlot({
    plot(amstat1()$Model,
         amstat1()$Price,
         xlab="Model",
         ylab="Price",
         pch=20)

  })
})

shinyServer（功能（输入、输出）{
数据%筛选器（模型==输入$Model）
})
输出$carpricePlot
input$Model
不能在反应函数之外使用（
renderPlot
是一个反应函数，请将包含
input$Model
的代码放在内部-或者更好：创建一个
reactive（）
，在
renderPlot
内部引用），谢谢！我现在明白了。我曾尝试创建一个反应，但我把它放在了错误的地方…在shinyServer中，但在renderPlot之前。在渲染区内移动它会清除它。然而，我仍然不清楚为什么在使用过滤器时需要反应，而在使用子集时则不需要反应……如果您将原始评论作为答案，我将接受它。供将来参考，使用dput共享数据集，这样人们就可以复制并粘贴它来复制您的工作了……我对此并不熟悉。这看起来与我尝试的非常相似，但我遇到了一个错误……类似于闭包类型的对象不可子集之类的东西……我会回去看一看。@jerH闭包不可子集当您在没有
（）
的情况下调用反应式，比如
amstat1$Model
我可以看到我犯了那种错误！感谢您在错误消息中提供翻译环。。。
shinyServer(function(input, output) {

  data <- read.csv("Amstat.csv", header = TRUE)
  amstat1<-reactive({
    data %>% select(Type,Price,Model ) %>% filter(Model == input$Model)
    })

  output$carpricePlot <- renderPlot({
    plot(amstat1()$Model,
         amstat1()$Price,
         xlab="Model",
         ylab="Price",
         pch=20)
