问题 I am getting the value [1] 0.7976529 by using verbatimTextOutput("oaccura") on ui.r and output$oaccura<-renderPrint({a3}) on server.r but i want 0.7976529. How to get data and add dynamic css. 回答1: Maybe you can use renderText instead library(shiny) a3 <- 0.7976529 ui <- fluidPage(verbatimTextOutput("oaccura")) server <- function(input, output, session) { output$oaccura <- renderText({a3}) } runApp(list(ui = ui, server = server)) 来源： https://stackoverflow.com/questions/40627799/how-to-get

问题 Friends, I would like you to help me with the following question: The executable code below generates clusters and shows in a table which industries are part of each cluster.
