Thanks a lot Marc for your detailed answer.

It creates a new .XLS file when used, overwriting an existing file of the same if it already exists. The intent is to provide the means to easily dump one or more data frames to an Excel file as a means to make data from R portable to others where an .XLS file makes sense as the vehicle, as an alternative to CSV files, etc. So the intent would be to have all of your data frames created and then use WriteXLS() to export them at once.
