[英]How to have R Shiny titlepanel pull text from server?
是否有某種方式可以使動態的titlePanel標題直接從如下所示的UI中提取? 如果不可能,是否有可能在titlepanel的正下方有第二行類似於titlepanel的行?
# Define UI ----
ui <- fluidPage(
##Whatever UI code here
titlepanel_text = paste0("Some string", variable_with_text)
)
# Define server logic ----
server <- function(input, output) {
titlePanel("title panel"),
#Rest of server code here
}
在服務器中渲染文本並在UI中獲取文本輸出:
library(shiny)
# Define UI ----
ui <- fluidPage(
##Whatever UI code here
titlePanel(textOutput("title_panel")),
sidebarLayout(
sidebarPanel(),
mainPanel(h1("text"))
)
)
# Define server logic ----
server <- function(input, output) {
output$title_panel <- renderText({
paste0("This is the date/time: ", Sys.time() )
})
}
shiny::shinyApp(ui, server)
您可以插入這種代碼來構建標題面板
# Application title
titlePanel(
fixedRow(
column(9,
"My Template",
fixedRow(
column(9,
paste0("Author : ", author)
),
column(3,
paste0("date : ", today(tzone = ""))
)
)
)
) ),
