すべてが大きすぎて投稿できませんが、これで十分です。

マイui.Rファイルが

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") 
    ) 
) 
)) 

が含まれていますそして、私のserver.rは

library(shiny) 
library(magrittr) 
library(dplyr) 

shinyServer(function(input, output) { 

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

    output$carpricePlot <- renderPlot({ 

    plot(Model, 
     Price, 
     xlab="Model", 
     ylab="prirce", 
     pch=20) 

    }) 
}) 

私はアプリを実行しようとすると、私はエラーメッセージ

エラーを取得しますが含まれていますin filter_impl（.data、dots）：アクティブなアクティブなコンテキストである なしでは、操作は許可されません。 （ しか反応式やオブザーバーの内部から行うことはできませんでした）

私は何かをつかんでいません。私がShinyを学ぼうとしたときに書いた他のアプリでは、フィルタの代わりにサブセットを使って基本的に同じことを達成しました... Shinyのフィルターを避けるべきですか？または私は何か間違っているのですか？まあ、明らかに私は間違ったことをしています！

Answer 1

あなたはUI（input$...）から変数を使用すると、あなたが反応性でそれを行う必要があります。

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) 

    }) 
})
