title: Create a chart with 4 boxplots comparing LungCapacity and the defined height groups in R
body: <p>This is my partial example. <code>boxplot(____,main="Lung Capacity vs. Height",ylab="Lung Capacity",las=3,col=c(5,2,3,4))</code>
  When I use <code>LungCap~Height</code> it gives me a scatterplot. How do I define the height groups.The four height groups are <code>59.9,65.4,70.3,81.8</code>. </p>
