title: R: Plot multiple box plots using columns from data frame
body: <p>I would like to plot an INDIVIDUAL box plot for each unrelated column in a data frame. I thought I was on the right track with <code>boxplot.matrix</code> from the <code>sfsmsic</code> package, but it seems to do the same as <code>boxplot(as.matrix(plotdata)</code> which is to plot everything in a shared boxplot with a shared  scale on the axis. I want (say) 5 individual plots.</p>
  
  <p>I could do this by hand like:</p>
  
  <pre><code>par(mfrow=c(2,2))
  boxplot(data$var1
  boxplot(data$var2)
  boxplot(data$var3)
  boxplot(data$var4)
  </code></pre>
  
  <p>But there must be a way to use the data frame columns?</p>
  
  <p>EDIT: I used iterations, see my answer.</p>
