    i m not sure what u really want to do but if ur looking for some subsample
   of dataset then u might wanna try this (say in case u want to resample ur
   dataset by column "id" in ur dataset then do


   dataset<-dataset[resample, ]

   note here n is the size of subset u wanna sample from ur dataset

   hope this helps.
