我試圖讓ggplot在Shiny中,當我運行代碼時沒有顯示錯誤,但圖形也沒有顯示出來。然而,側面板和其他一切確實如此。RShiny:ggplot沒有顯示,但沒有顯示錯誤
這裏有一個情節
c<-ggplot(avgscore,aes(x=V1,y=V2))
c+geom_bar(stat="identity", position="identity")+ggtitle('Average Score Difference from TimeID to the Following TimeID')+xlab('TimeID')+ylab('Average Score Difference')
c<-ggplot(avgcorrect,aes(x=V1,y=V2))
c+geom_bar(stat='identity',position = "identity")+ggtitle('Average Correctness Difference from TimeID to the Following TimeID')+xlab('TimeID')+ylab('Average Correctness Difference')
任何幫助將是巨大的我的非閃亮的代碼!
server.R
library(shiny)
library(ggplot2)
avgscore <- read.csv("avgscore.csv")
avgcorrect <- read.csv("avgcorrect.csv")
avgscore$V2 <- as.numeric(as.character(avgscore$V2))
avgcorrect$V2 <- as.numeric(as.character(avgcorrect$V2))
shinyServer(function(input, output) {
datasetInput <- reactive({
switch(input$dataset,
"Average Score Difference" = avgscore,
"Average Correctness Difference" = avgcorrect)
})
output$view <- renderPlot({
p <- ggplot(datasetInput(),aes(x=input$V1,y=input$V2))
p <- p + geom_bar(stat="identity", position="identity")+xlab('TimeID')+ylab('Average')
print(p)
})
})
ui.R
shinyUI(pageWithSidebar(
headerPanel("Differences from Time ID to following TimeID"),
sidebarPanel(
selectInput("dataset", "Choose:",
choices = c("Average Score Difference", "Average Correctness Difference"))
),
mainPanel(
htmlOutput("view")
)
))
這裏是我的數據
dput(avgscore)

'renderPlot'應該去'plotOutput',不'htmlOutput '。 –
完美,謝謝 – Una
沒問題。繼續並接受你的回答以關閉這個問題。 –
