title: How to use position_jitter_tern() in ggtern() in R?
body: <p>I am creating a simple ternary plot.</p>
  <pre><code>ggtern(data=data.frame(x=c(0.1,0.1),y=c(0.2,0.2),z=c(0.7,0.7)),aes(x,y,z)) + geom_point()
  
  </code></pre>
  <p>How can I jitter the point so that the plot will display two points?
  I tried using position_jitter_tern like so: but it isn't changing anything.</p>
  <pre><code>ggtern(data=data.frame(x=c(0.1,0.1),y=c(0.2,0.2),z=c(0.7,0.7)),aes(x,y,z, position_jitter_tern(0.1,0.1,0.1))) + geom_point()
  
  </code></pre>
