xls writer in a loop

Dear users,
I am looking for a way to use the xls writer node but in a loop mode, where each set of data charaterized by the iteration number would be appended in a new sheet in the same xls file. If it is not possible, can you provide a script in an R snippet to do that?
Any help would be appreciated, thank you
