title: How to use multiple numbers in SelectInput in Shiny
body: <p>I have a question regarding Shiny and the SelectInput function. This is my selectinput right now: </p>
  
  <pre><code> selectInput("top1", label = h3("TOP500"),
                       c("TRUE" = 1,
                         "FALSE" = 0,
                         "BOTH" = 0|1), selected = 0)
  </code></pre>
  
  <p>I used it for the following function:</p>
  
  <pre><code>filter(sales_category_id == input$top1)
  </code></pre>
  
  <p>This is a table who gets mutated by dplyr and in the end i want to choose between sales_category_id 0,1 or both. </p>
  
  <p>Can someone please help me out? This is not working and everything i tried did not give me the correct result.  </p>
  
  <p>First question by the way, so if i wrote something unclear please let me know :) </p>
  
  <p>EDIT: </p>
  
  <p>Since the id can only be 0 or 1 i fixed it this way:</p>
  
  <pre><code>selectInput("top1", label = h3("TOP500"),
                       c("TRUE" = 0,
                         "FALSE" = 1,
                         "BOTH" = 2), selected = 0)
  
  filter(sales_category_id != input$top1
  </code></pre>
  
  <p>I am still intrested in an answer though. </p>
