title: Error in La.svd(x, nu, nv) : error code 1 from Lapack routine 'dgesdd' when using stability function in ClustOfVar
body: <p>I tried to apply stability function in ClustOfVar package and got an error message as below:</p>
  
  <pre><code>Error in La.svd(x, nu, nv) : error code 1 from Lapack routine 'dgesdd'.

  <p>I intended to do the variable clustering on a data set including both quantitative and qualitative variables. The R codes I uses are shown as below. At first I use the data directly (i.e., without standardization of the quantitative variables) and got the error message when running the <code>stability</code> function). Then I scale the quantitative variables and rerun the codes and got the same error message. Would someone give a suggestion how to fix the problem? Also, I do not think it need no step to standardize the quantitative variables because the <code>hclustvar</code> function should contain the standardization, right?</p>
  
  <pre><code>X.quanti&lt;-Data4Cluster[, c(9:28)]
  X.quanti2&lt;-scale(X.quanti, center=TRUE, scale=TRUE)
  X.quali&lt;-Data4Cluster[, c(1:4,8)]
  
  tree&lt;-hclustvar(X.quanti,X.quali)
  plot(tree)
  stab&lt;-stability(tree, B=40)
  
  tree2&lt;-hclustvar(X.quanti2,X.quali)
  plot(tree2)
  stab&lt;-stability(tree2, B=40)
  </code></pre>
