title: Selecting Percentile curves using gamlss::lms in R
body: <p>I am using example code from gamlss package to draw percentile curves: </p>
  
  <pre><code>library(gamlss) 
  data(abdom)
  lms(y,x , data=abdom, n.cyc=30)
  </code></pre>
  
  <p><img src="https://i.stack.imgur.com/HKqLi.png" alt="enter image description here"></p>
  
  <p>It is drawing its own set of percentile curves. How can I choose to draw only 10th, 50th and 90th percentile curves? Also I want to avoid plotting of points so that only curves are drawn.
  Thanks for your help.</p>
