title: Error in eigen(corr) : infinite or missing values in 'x' when making a 'Correlation matrix circles plot'
body: <p>I would like to make a correlation matrix like the one below. However, R keeps telling me </p>
  
  <pre><code>'Error in eigen(corr) : infinite or missing values in 'x''
  </code></pre>
  
  <p><a href="http://gallery.r-enthusiasts.com/graph/Correlation_matrix_circles,152" rel="noreferrer">Correlation matrix circles</a></p>
  
  <p>I think this may be caused by NA values in my matrix. However, when I try to remove them by adding</p>
  
  <pre><code>'na.rm=TRUE,' it doesnt seem to help
  
  circle.corr( cor(Plant, na.rm=TRUE,), order = TRUE, bg = "gray50", 
      col = colorRampPalette(c("blue","white","red"))(100) )
  </code></pre>
  
  <p>I have already loaded the function provided in the link above</p>
  
  <p>Is it possible to create a new data.frame with the NA's removed? if so, how?</p>
