问题 I have a datatable in R Shiny, and one of the columns, Keywords, contains multiple entries for some rows, separated by a comma. I would like these multiple entries to be individually searchable. The default search feature for datatable treats these entries as one, long, single item. For example, row 2's value for the column Keywords is "Keyword1, Keyword2". I would like the user to be able to search for either "Keyword1" OR "Keyword2" and find row 2. Currently, the default search bar in

问题 Here is the data frame sports=data_frame(question=c("<h5>This gives you more information about pro Football What position would you prefer to play in pro Football?</h5>", "</h5>This gives you more information about pro Soccer What position would you prefer to play in pro Soccer?</h5>", "</h5>This gives you more information about pro Hockey What position would you prefer to play in pro Hockey?</h5>"), `Expected Money`= c(list(c('First Year = 10', 'First 3 Years= 50')), list(c('First Year = 15'

问题 I am working on a task similar to those described in RStudio Shiny list from checking rows in dataTables and Shiny - checkbox in table in shiny - embedding checkboxes within a DT table. My application is a little more complicated though - there are multiple tabs, the table can be filtered, and the content depends on reactive values elsewhere. I have been able to get the checkboxes working with a little JS, but have found if I have another DT table in another tab, the target table does not

问题 I am trying to build a shiny app that uses dynamically created inputs within a data.table with the help of the DT package. In the reproducible example below, the shiny-input input$Sel_Group_1 created within the DT-output depends on the value chosen in the shiny-input input$selectGroup (values a or b). The selected item (values c,d,f,g) are then shown in the textoutput output$selectedItem . When I initially launch the app everything works fine, but as soon as I update the value in input

问题 Is there a way to have the selected row(s) in a shiny datatable (DT) be available for the user to copy (Ctrl+C) to their clipboard. Ideally it would also supply the data table's column names or headers. UPDATE global.R library(rclipboard) library(shiny) ui.R: ... rclipboardSetup(), ... uiOutput("copy"), server.R: output$copy = renderUI({ s = input$orders_rows_selected rclipButton("copybtm","Copy",data()[s,],icon("clipboard")) }) 回答1: Here is how to get a button to copy the selected rows. And

问题 I have a datatable in shiny. When a user selects a certain row, I want to display some other data based on the selected row in a new window. I tried to use shinyBS package but I could not use it without action button and I don't want to include action button. I want the pop up to display when a row is selected. Any ideas? mymtcars = head(mtcars) for_pop_up = 1:6 app <- shinyApp( ui = fluidPage( DT::dataTableOutput("mydatatable") ), server = shinyServer(function(input, output, session) {

问题 I have created a table which looks as per screenshot. How could I add an excel like filter button where I could select multiple specific items of the list? And code is the following: DT::datatable(current_list, rownames = FALSE, filter = 'top', options = list(pageLength = 50,lengthChange = FALSE,autoWidth = FALSE,escape=FALSE, searching = TRUE, columnDefs = list(list(className = 'dt-center', targets = 0:1), list(width = '30px', targets = 0:0), list(width = '270px', targets = 1:1) ) ) ) 回答1:

问题 I'm using datatable function from DT package in R Shiny and I want that the user of my app can edit the column names (the variable names). Is there any option to do that? For now I'm using a text input "old_var_name", a text input "new_var_name" and an actionbutton "update_variable_name". But at this point, I'm only able to change on variable name at the time. I want the user to be able to change as much as variable names he wants. Server: tab <- eventReactive(input$import,{ inFile <- input
