% % in dplyr - SoojungHong/R_General GitHub Wiki

%>% in dplyr is similar to pipe in unix it created continuity.

For example, a = combined_data_set %>% group_by(Outlet_Identifier) %>% tally() means, output of combined_data_set will go in group_by and result of group_by will go to tall() and final output is assigned to a. This gives you handy and easy way to use functions in series without creating variables and storing intermediate values.
