Interactively change the selectInput choices

Question

Originally I create this shiny interface that takes in a parameter \"company id\" and \"date\", but here we have a problem: most people dont know the companies we work with

Answer 1

In Shiny version 0.8 (where I have tested it), in server.R add the following:

shinyServer(function(input, output, session) {

  observe({
    # This will change the value of input$partnerName to searchResult()[,1]
    updateTextInput(session, "partnerName", 
                    label = "Select your choice", 
                    value = searchResult()[,1])
  })

})

Now the function within shinyServer has additional argument session.

You can skip the label if you don't need to change it.

You don't need to change anything in ui.R.
