title: formal argument "data" matched by multiple actual arguments in R
body: <p>When I run the following codes in R, </p>
  
  <pre><code>library(mclust)
  data(iris)
  mc &lt;- Mclust(iris[,1:4], 3)
  plot(mc, data=iris[,1:4], what="classification",dimens=c(3,4))
  table(iris$Species, mc$classification)
  </code></pre>
  
  <p>I got an error meesage for the <code>plot</code>:</p>
  
  <pre><code>Error in coordProj(data = data, what = "classification", parameters = object$parameters,  : 
    formal argument "data" matched by multiple actual arguments
  </code></pre>
  
  <p>I am not sure what went wrong with the data subset <code>data=iris[,1:4]</code>. Any suggestions? Thanks!</p>
