title: Remove dots from cluster plot (factoextra)
body: <p>Is there a way to remove the dots from the <code>fviz_cluster</code> function of the factoextra package (plotting package of factominer).</p>

  <p>As you can see, this is a bit messy with the dots, I would like to keep the cluster centers and ellipsoids only.</p>
  
  <p><code>fviz_cluster(HCPC9CL, repel = FALSE, geom = "point", show.clust.cent = TRUE, ellipse.type = "norm", palette = trololo, ggtheme = theme_minimal(),
  main = "Factor map")</code></p>
