title: Export data into specific cells in Excel sheet
body: <p>I need to export a data frame in R to an Excel sheet, which can be done via: </p>
  
  <pre><code>require("xlsx")
  write.xlsx(x, file, sheetName="Sheet1", col.names=TRUE, 
      row.names=TRUE, append=FALSE, showNA=TRUE)
  </code></pre>
  
  <p>My exported data will then be pasted beginning in cell "A1" of the Excel sheet. I can also set <code>append=TRUE</code> so the data will be added at the end of the sheet.</p>
  
  <p>Is there a possibility to put it into a <strong>specific cell</strong>? I need to export the data frame to a range beginning at cell <code>C10</code>. Is this possible?</p>
  
  <p><strong>Update:</strong>
  The sheet contains data in rows <code>1-9</code> as well as columns <code>A-B</code>. Therefore it is not possible to just add empty cells to the data frame and paste it into the excel sheet, because those empty cells would erase the data.</p>
