title: I'm having difficulties with plotting a spefic row
body: <p>I have a Dataset and I want to plot a specific row from it.</p>
  
  <p>I manged to do it in a crude way like this:</p>
  
  <pre><code>person7_loss = c(weigh_loss$Jan[weigh_loss$Individuals == "Person 7"], 
               weigh_loss$Feb[weigh_loss$Individuals == "Person 7"],
               weigh_loss$Mar[weigh_loss$Individuals == "Person 7"],
               weigh_loss$Apr[weigh_loss$Individuals == "Person 7"],
               weigh_loss$Mai[weigh_loss$Individuals == "Person 7"],
               weigh_loss$Jun[weigh_loss$Individuals == "Person 7"],
               weigh_loss$Jul[weigh_loss$Individuals == "Person 7"],
               weigh_loss$Aug[weigh_loss$Individuals == "Person 7"],
               weigh_loss$Sep[weigh_loss$Individuals == "Person 7"],
               weigh_loss$Oct[weigh_loss$Individuals == "Person 7"],
               weigh_loss$Nov[weigh_loss$Individuals == "Person 7"],
               weigh_loss$Des[weigh_loss$Individuals == "Person 7"])
  </code></pre>
  
  <p>But I figure that there's a simpler way to do it.</p>
  
  <p>I imagined something like:</p>
  
  <pre><code>person1 = weigh_loss[1,5:16]
  plot(x = person1, type = "h", ylim = c(0, 120), ylab = "Þyngd",
       xlab = "Mánuður")
  </code></pre>
