title: OutOfMemoryError (Java) : Java heap space
body: <p>I'm trying to add 10 more rows at the end of an excel table (currently 27k rows long)</p>
  
  <pre><code>options(java.parameters = "-Xmx4g" ) ; 
  library(XLConnect) ;
  writeWorksheetToFile("H:/R/myfile.xlsx",DataTable,sheet="Sheet1",startRow=row1,startCol=1,header=FALSE,rownames=FALSE) 
  </code></pre>
  
  <p>after some seconds I receive the error </p>
  
  <p>OutOfMemoryError (Java) : Java heap space</p>
  
  <p>How can I fix this? Shouldn't options(java.parameters = "-Xmx4g" ) work?</p>
