using Source() in Shiny

Question

I have a working R application that I want to make available online using Shiny. My application receives a file as input, so the client uploads the file through ui.R. server

Answer 1

To use source in your shiny app you need to invoke the local = TRUE argument so in this case:

shinyServer(function(input, output) {

   output$contents <- renderTable({
   inFile <- input$file1
   if (is.null(inFile))
      return(NULL)
   else{
      tdata <- as.matrix(   read.table(inFile$datapath))
      head(tdata, n = 2)
      source("./CODE/run_myApp.r", local = TRUE)
   }
  })
})
