title: Reshape multiple response survey data in R
body: <p>I am working with survey data in R that has a multiple response question.</p>
  
  <p>Currently my data looks like: </p>
  
  <pre><code>Q1_1  Q1_2  Q1_3 Q1_4
  1       1    0    0
  1       0    0    0 
  0       1    1    0 
  1       0    0    0
  </code></pre>
  
  <p>I would like it to look like this so I can create a bar chart comparing the counts:</p>
  
  <pre><code>Q1     Count 
  Q1_1     3
  Q1_2     2
  Q1_3     1 
  Q1_4     0 
  </code></pre>
  
  <p>I am a newcomer to R and have no idea where to start. How would I restructure this?</p>
