title: R '.doSnowGlobals' not found
body: <p>I am working with the package random uniform Forest. I am trying to run the examples provided in the documentation:</p>
  
  <pre><code>data(iris)
  XY = iris
  p = ncol(XY)
  X = XY[,-p]
  Y = XY[,p]
  iris.ruf = randomUniformForest(Species ~., XY, threads = 1)
  </code></pre>
  
  <p>But I get this error:</p>
  
  <pre><code>Error in checkForRemoteErrors(lapply(cl, recvResult)) : 
  7 nodes produced errors; first error: object '.doSnowGlobals' not found
  </code></pre>
  
  <p>I googled and found that this is because it is trying to use paralell computing and it does not find something it needs. I have never used paralell computing so I did not understand the explanations I have found and I do not know how to fix this problem. I also read "<a href="https://stackoverflow.com/questions/25079527/error-object-dosnowglobals-not-found">error: object &#39;.doSnowGlobals&#39; not found?</a>". </p>
  
  <p>According to the manual using "threads = 1" deactivated paralell computing, but I get the error anyways. </p>
  
  <p>I have also checked and the packages paralell and doParallel are loaded. </p>
  
  <p>I do not really need paralell computing and I do not know if I am "connected" to other computers, so I am not sure If that would even work. Would there be an easy way do deactivate paralell computing? Or another alternative for making this work?</p>
