title: genRandomClust does not seem to be generating random clusters
body: <p>I have been trying to generate som random clusters using the package clusterGeneraion. I keep getting the same output in terms of class distribution and the same clusters using kmeans. This is the code:</p>
  
  <pre><code>library(factoextra)
  library(clusterGeneration)
  
  nclust = 3
  feat = 3
  
  data = genRandomClust(numClust=nclust,
                          sepVal=-0.1, numNonNoisy=feat,
                          clustszind=2)
  
  data = as.data.frame(cbind(data$datList$test_1, data$memList$test_1))
  colnames(data)[feat+1] = "class"
  table(data$class)
  
  km.res &lt;- eclust(data[,-(feat+1)], "kmeans", k = nclust, nstart = 25, graph = FALSE)
  table(km.res$cluster, data$class)
  </code></pre>
  
  <p>which always gives me the following</p>
  
  <p>Classdistribution</p>
  
  <pre><code>  1   2   3 
   77 102 153 
  </code></pre>
  
  <p>Clusters from kmeans</p>
  
  <pre><code>      1   2   3
    1   4  81   1
    2  70   7  14
    3   3  14 138
  </code></pre>
  
  <p>Why are these not random?</p>
