我有一個數據集，顯示了一組網站，如果每一個定期使用（是/否每個網站），當它最後使用（yesteraday /上週/ ...每個網站）。 我想用一個動態的用戶界面來構建一個閃亮的儀表板，該界面顯示兩個選定網站相鄰的社會人口統計網站配置文件，通過網站使用或網站覆蓋進行過濾。動態UI的閃亮的儀表板。動態用戶界面與多個selectInput每井面板
結構：
選擇濾波器類型（1）網站使用VS（2）網頁到達
在 「網站使用」 的情況下：
選擇第一網站（web1-web5）
選擇第二個網站（web1-web5）
在網站河段的情況下：
選擇第一個網站（WEB1-WEB5）
選擇到達第一個網站（每日，每週，每月，每年）
選擇第二個網站（WEB1-WEB5）
選擇河段第二個網站（每日，每週，每月，每年）
我嘗試以下解決方案從Rstudio： Dynamic UI Guide from Rstudio
我的問題是，使用「開關」的解決方案只允許每個wellPanel一個selectInput字段。像這樣，我無法爲第二個網站添加額外的過濾器。有沒有使用開關的解決方法或不同的解決方案？

gender <- factor(sample(1:2, 5, replace = TRUE),
levels = c(1,2,99), labels = c("Male", "Female", "Missing Value"))
age <- sample(18:55, 5, replace = TRUE)
web1 <- factor(sample(1:2, 5, replace = TRUE), levels = c(1,2,99),
labels = c("Yes", "No", "Missing Value"))
web2 <- factor(sample(1:2, 5, replace = TRUE), levels = c(1,2,99),
labels = c("Yes", "No", "Missing Value"))
web3 <- factor(sample(1:2, 5, replace = TRUE), levels = c(1,2,99),
labels = c("Yes", "No", "Missing Value"))
web4 <- factor(sample(1:2, 5, replace = TRUE), levels = c(1,2,99),
labels = c("Yes", "No", "Missing Value"))
web5 <- factor(sample(1:2, 5, replace = TRUE), levels = c(1,2,99),
labels = c("Yes", "No", "Missing Value"))
web1Rch <- factor(sample(1:4, 5, replace = TRUE), levels = c(1,2,3,4,99),
labels = c("Daily", "Weekly", "Monthly", "Yearly", "Missing Value"))
web2Rch <- factor(sample(1:4, 5, replace = TRUE), levels = c(1,2,3,4,99),
labels = c("Daily", "Weekly", "Monthly", "Yearly", "Missing Value"))
web3Rch <- factor(sample(1:4, 5, replace = TRUE), levels = c(1,2,3,4,99),
labels = c("Daily", "Weekly", "Monthly", "Yearly", "Missing Value"))
web4Rch <- factor(sample(1:4, 5, replace = TRUE), levels = c(1,2,3,4,99),
labels = c("Daily", "Weekly", "Monthly", "Yearly", "Missing Value"))
web5Rch <- factor(sample(1:4, 5, replace = TRUE), levels = c(1,2,3,4,99),
labels = c("Daily", "Weekly", "Monthly", "Yearly", "Missing Value"))
popWeight <- sample(1000:1500, 5, replace = TRUE)
df <- data.frame(gender, age, web1, web2, web3, web4, web5, web1Rch,
web2Rch, web3Rch, web4Rch, web5Rch, popWeight)
df
下面的代碼是多遠我得了。但是我無法創建一個動態UI，允許我爲第二個網站使用圖形填充第二個儀表板列。開關不允許放置兩個selectInput字段。
示例代碼
library(shiny)
library (tidyr)
library (dplyr)
library(ggplot2)
library(scales)
# Create Two Versions of Data Frame for "Regular Usage" and "Reach"
dfRegular <- df[,c(1:7,13)] %>%
gather(web, value, -age, -gender, -popWeight)
dfReach <- df[,c(1:2,8:13)] %>%
gather(web, value, -age, -gender, -popWeight)
# Code for Shiny App
ui <- fluidPage(
titlePanel ("Website Profile"),
br(),
fluidRow(
column(2,
wellPanel(
selectInput(inputId = "evalType", label = "Choose Evaluation",
choices = c("Regular", "Reach"))
),
wellPanel(uiOutput("ui"))
),
column(5, plotOutput("Gender")),
column(5, plotOutput("Gender1"))
)
)
server <- function(input, output) {
# Output UI
output$ui <- renderUI({
if(is.null(input$evalType))
return()
switch(
input$evalType,
"Regular" = selectInput(
inputId = "websiteName", label = "Choose first Website",
choices = unique(dfRegular$web)),
"Reach" = selectInput(
inputId = "reachWeb", label = "Choose Reach (second Website)",
choices = c("web1Rch", "web2Rch", "web3Rch", "web4Rch", "web5Rch"))
)
})
output$evalTypeText <- renderText({
input$evalType
})
dfInput <- reactive({
dfRegular %>% filter(web == input$websiteName & value == "Yes")
})
output$Gender <- renderPlot({
df1 <- dfInput()
ggplot(df1) +
aes(x = gender, y = popWeight/sum(popWeight)) +
stat_summary(fun.y = sum, geom = "bar") +
scale_y_continuous("Population (%)", labels = scales::percent)
})
dfInput <- reactive({
dfRegular %>% filter(web == input$websiteName & value == "Yes")
})
output$Gender1 <- renderPlot({
df1 <- dfInput()
ggplot(df1) +
aes(x = gender, y = popWeight/sum(popWeight)) +
stat_summary(fun.y = sum, geom = "bar") +
scale_y_continuous("Population (%)", labels = scales::percent)
})
}
shinyApp(ui = ui, server = server)
謝謝你完美的作品。但由於某種原因，它弄亂了我的列布局。 UI顯示在圖形上方而不是旁邊。 – Finn
只需要移動'fluidRow'的'''，看更新 –
