Dear R-friends,    

  I have a table data structured by group, subgroups, records and attributes. For each group and subgroup I have differente number of records (more than 200). I need bootstrap 100 records for each group/subgroup combinations and repeat it a big number of times.    

  Could someone of you help me on this hard (almost for me) task.    

  Kind regards,
