title: How can I make legend next to my piechart in R?
body: <p>I have made a piechart in R with the next code:</p>
  
  <pre><code>#make slices
  slices &lt;- c(19, 26, 55)
  
  # Define some colors 
  colors &lt;- c("yellow2","olivedrab3","orangered3")
  
  # Calculate the percentage for each day, rounded to one decimal place
  slices_labels &lt;- round(slices/sum(slices) * 100, 1)
  
  # Concatenate a '%' char after each value
  slices_labels &lt;- paste(slices_labels, "%", sep="")
  
  # Create a pie chart with defined heading and custom colors and labels
  pie(slices, main="Sum", col=colors, labels=slices_labels, cex=0.8)
  
  # Create a legend at the right   
  legend("topright", c("DH","UT","AM"), cex=0.7, fill=colors)
  </code></pre>
  
  <p>But I want the legend next to my piechart. I have also tried the following code: <code>legend("centreright", c("DH","UT","AM"), cex=0.7, fill=colors)</code>.
  But this does not give me a legend next to my pie chart.</p>
  
  <p>Which code do I have to use to make a legend next to my pie chart in the middle?</p>
