action-button

问题 Using R shiny, is it possible to link selectInput item to open file action button ? I would like to adapt onclick argument of action button to achieve it. Please find below a reproductible example: Supposing we have "file_1.pdf" and "file_2.pdf" on "www" folder, how can I open the file corresponding to select Input choice ? library(shinydashboard) library(shiny) ui <- dashboardPage( dashboardHeader(title = "Open file app"), dashboardSidebar(), dashboardBody( fluidRow( selectInput(inputId =

问题 Currently my actionButton is taking in user input through drop down lists, and then when the actionButton is pressed it outputs this to a csv file. However, if the user only inputs 2 out of the 5 drop down lists and presses the actionButton this will still go to the csv file. How can I make it so it only accepts the actionButton if all inputs are given? I am using observeEvent(). 回答1: if you use the packages shinyjs you can deactivate the button when not all inputs are given with something

问题 I'm trying to build an app in R shiny where users can learn details about points on a map. When users click on a point, a popup shows some initial details and then an ActionButton (or ActionLink). When the user clicks on that ActionButton, ObserveEvent reactive launches a modal dialog displaying more information about that point. I have the maps, action buttons, and modal dialogs in place. However, I can't figure out how to "assign" each ActionButton to its point/popup on the map. Is there a

问题 Here is a sample code to generate a plot upon clicking the actionButton. shinyApp( shinyUI(fluidPage( inputPanel( numericInput("n", "n", 10), actionButton("update", "Update") ), plotOutput("plot") )), shinyServer(function(input, output) { values <- reactiveValues() values$data <- c() obs <- observe({ input$update isolate({ values$data <- c(values$data, runif(as.numeric(input$n), -10, 10)) }) }, suspended=TRUE) obs2 <- observe({ if (input$update > 0) obs$resume() }) output$plot <- renderPlot({

问题 Using RStudio 1.0.136 and R Shiny 0.14.2, I am trying to create a data table that has an action button on each row, and when a button is clicked a popup will appear. My code is currently working, except you cannot click the same button twice in a row. I have posted 2 versions of example code below: library(shiny) library(DT) library(shinyBS) shinyApp( ui <- fluidPage( DT::dataTableOutput("data"), uiOutput("modal") ), server <- function(input, output,session) { shinyInput <- function(FUN, len,

问题 I have the shiny app below in which I have 3 file inputs and 2 actionbuttons. The 1st submit button 'submit' is used to trigger the tree plot and the 2nd 'reset' to reset every file input. When the 1st actionbutton is empty I get a warning message. The tree is displayed only when the all of the files are loaded or 1st and 2nd are loaded or only 1st is loaded. Based on this I have crated an if statement which you can find in line 120. The issue is that while the app works fine it does not
