This is simply fantastic. I have gone through so many forums - R help, Stats exchange etc etc and in most of the cases ppl bluntly say go and brush ur skills and don't believe in answering easy questions posted by newbies. However in the video above you have taken the pain to explain step by step how dyply is working. Really helped. In 11:31 we are filtering where DepDelay >60 so can we do a similar between 2 columns. I did so but received an error as they were factors. Thanks,

Just a quick comment about the "group_by %>% summarise %>% arrange" process you describe in 23:37. It seems to have changed behaviour (maybe the new R version?) and returns the arranged values based on the groups you specified before. It needs an ungroup() function before the arrange, in order to return the results we want. Let me know if this is the proper way to do it, or if I am missing something...
