Data Structures Feedback

  1. Message:
  2. Thanks for an informative and interested podcast . I have learned R
  3. alone by reading in Internet, and being able to hear an actual voice
  4. is a refreshing experience.
  5. I'm catching up with the past podcasts and have completed only 3.
  6. However, I have a few questions y data structures.
  7. Some data aggregation functions return a Table class that I don't know
  8. how to use other than printing it. Therefore I have avoided them in
  9. favor of other functions like those in the plyr package.
  10. I have also read things about data.table, regarding it being a
  11. newer/better alternative to dataframe.
  12. Can you talk us about those two data structures?
  13.  
  14. Thanks!
  15. Eric
