title: Past Text for multiple Select Input (R; Shiny)
body: <p>I am working on a shiny app and created a simplified version of my problem below. Pretty much I want to have a input select of different options (A,B,C,D) and when any or all of these options are selected then prints out different texts. Currently, if I select all the options then only "Your Idael A Value is" posts. </p>
  
  <pre><code>library(shiny) 
  shinyServer( function(input, output) {
    output$whatever&lt;-renderText( {
      if( input$test=="a") {
        ("Your ideal A value is")
      }
      else if (input$test=="b") {
        ("Your ideal B value is:")
      }
      else if (input$test=="c") {
        ("Your ideal C value is:")
      }
      else if(input$test=="D") {
        ("Your idea D value is:")
      }
    }
    )
  }
  
  )
  </code></pre>

  <pre><code>    library(shiny)
  
     shinyUI(fluidPage(
     headerPanel(title="pratice"),
     sidebarLayout(
     sidebarPanel(
     selectInput("test",label="Test",multiple = TRUE, 
     choices=list("a","b","c","d")
     )),
     mainPanel(
    textOutput("whatever")
    )
