title: R studio "pavo" package: can i plot two data in the same tetrahedral colorspace using function "tcsplot"?
body: <p>I'm using the "pavo" package in R studio to create a tetrahedral colorspace plot using function "tcsplot". I want to ask that how can I write to combine two respectively data in the same tetrahedral colorspace plot</p>
  
  <pre><code>tcsplot(data1, 
      size = 0.01, 
      alpha = 1, 
      col = "green", 
      vertexsize = 0.02, 
      achro = TRUE, 
      achrosize = 0.01, 
      achrocol = "grey", 
      lwd = 1, 
      lcol = "lightgrey", 
      new = FALSE, 
      hspin = FALSE, 
      vspin = FALSE, 
      floor = F, 
      grid = TRUE, 
      fill = TRUE
  )
  </code></pre>
