I tried to write the dataset into a parquet or feather objects but RStudio always crashes because of memory issue. I have 8 core computer and 32 GB ram. Is there a way to write the data into e.g. feather format in a more efficient way without crashing?

   Hi @eitsupi and all,
   
   The above solution wherein the argument "delim = \t" is added worked for me when I received an almost identical error to @elgabbas.
   
   Thanks!
