Shiny

问题 I have a large Shiny application that has a number of prompts, then generates tables and plot based on those inputs. I don't use rmarkdown or knitr or anything to format the output. I just use the standard Shiny elements (sidebarPanel, mainPanel, etc.). For the plots and tables I use the standard reactive renderPlot and renderTable objects. I'm looking for an easy way to have a button called "Export to PDF" that exports the elements on the page to a PDF document. I've looked into using knitr

问题 This seems like a very simple question, but I have searched and searched! I am using selectize to select multiple items from a list in a selectInput dropdown menu. Below it I have a Submit button to perform some action on the list. As you add multiple entries, the selectInput box grows, and the button dynamically moves down the sidebar, but when you open the dropdown menu to see the list of options, the Submit button is hidden. I would like the button to dynamically jump down and stay visible

问题 I'm trying to populate dynamically generated tabs with plots made from a loop but can't get the tabs to populate with all of the plots generated in the loop. shinyUI(pageWithSidebar( headerPanel("Dynamic number of plots"), sidebarPanel( ), mainPanel( # This is the dynamic UI for the plots uiOutput("IndividualPlots") ) )) server <- function(input, output) { output$IndividualPlots <- renderUI({ if (is.null(input$data_cqt0)) { return() } plot_content() shiny:::buildTabset( id = "t", lapply(1
