Hello Trying to create a dashboard to upload csv files and get summary statistics of each variable. Below is my UI and server codes. library(shiny) library(shinydashboard) shinyUI( dashboardPage( dashboardHeader(title="Feedback Analysis"), dashboardSidebar( fileInput("file","Upload CSV …

Yes, tried with this but still the error persist.

If I'm reading it right, it looks like you are trying to use the column names from the object values as the selectInput options in the UI. You are receiving this error as the object values is defined within server making the names inaccessible in the shinyUI. The function updateSelectInput (see link…

Thank you for the response. As per your suggestion, I have made changes to the code, please let me know where I am going wrong as I get same error. library(shiny) library(shinydashboard) shinyUI( dashboardPage( dashboardHeader(title="Feedback Analysis"), dashboardSidebar( fileInput("file…

I'm not sure if... [image] KafeelI: values <- reactiveValues(df_data = NULL) ..is necessary. What happens when you read the data in as a reactive object? (See below) server <- shinyServer(function(input,output,session){ # observeEvent for input$file observeEvent(input$file, { …

Thanks a lot for your instructions. By using only reactive() function, either I get an error "could find function" or after uploading the data nothing displays in the tab as below [image] Can you please help me with an example how can I get summary by changing the variables, after uploading csv …

[image] KafeelI: Here I am unable to see the data once I upload Moving the output$data.table <- renderTable(...) into the observeEvent for input$file will do the trick. # observeEvent for input$file observeEvent(input$file, { # render tables at file upload output$data.frame <- r…

Thanks a lot for your help. I will work little more on summary statistics part and how to show in a separate page and get back to you.
