title: Par() function in R,plot not shown
body: <p>Hey there stackoverflow geeks, I am working with a dataset in R language using R studio. I want to display my pareto charts <em>side by side</em> so better analysis can be done.</p>
  <p>When I use <strong>par()</strong> function , i only get the first plot with an empty white space on right, can anyone please help me with what the issue is?</p>
  <pre><code>
  
  
  library(qcc)
  
  stateRegion &lt;- table(state.region)
  stateDivision &lt;- table(state.division)
  
  par(mfrow=c(1,2))   
  
  pareto.chart(stateRegion)          #only this one appears
  pareto.chart(stateDivision)        #this one is not plotting
  
  </code></pre>
  <p><strong>EDIT</strong>
  The code is working with all other plots except pareto chart/plot.
  Please help.</p>
