HTML 输出由 summarytool::dfSummary 函数创建。
summarytools 使用 Bootstrap 的样式表生成独立的 HTML 文档,这些文档可以使用通用的 print() 函数显示在 Web 浏览器或 RStudio 的查看器中。
当 HTML 在选项卡面板上呈现时,整个 UI 都会发生变化。有没有办法在不改变 UI 的情况下在标签面板上呈现 HTML?
library(summarytools)
ui <- fluidPage(
titlePanel("dfSummary"),
sidebarLayout(
sidebarPanel(
uiOutput("dfSummaryButton")
),
mainPanel(
tabsetPanel(
tabPanel("Data Input",
dataTableOutput("dataInput"),
br(),
verbatimTextOutput("profileSTR")),
tabPanel("dfSummary Output",
htmlOutput("profileSummary")))
)
)
)
server <- function(input, output, session) {
#Read in data file
recVal <- reactiveValues()
dfdata <- iris
#First 10 records of input file
output$dataInput <- renderDataTable(head(dfdata, n = 10), options = list(scrollY = '500px',
scrollX = TRUE, searching = FALSE, paging = FALSE, info = FALSE,
ordering = FALSE, columnDefs = list(list(className = 'dt-center',
targets = '_all'))))
#str() of input file
output$profileSTR <- renderPrint({
ProStr <- str(dfdata)
return(ProStr)
})
#Create dfSummary Button
output$dfSummaryButton <- renderUI({
actionButton("dfsummarybutton", "Create dfSummary")
})
### Apply dfSummary Buttom
observeEvent(input$dfsummarybutton, {
recVal$dfdata <- dfdata
})
#dfSummary data
output$profileSummary <- renderUI({
req(recVal$dfdata)
SumProfile <- print(dfSummary(recVal$dfdata), omit.headings = TRUE, method = 'render')
SumProfile
})
}
