dplyr in r | anti_join , semi_join, inner_join, left_join dplyr, right_join dplyr, full_join dplyr
How does dplyr semi_join and anti_join dplyr functions work?

Instead, it returns rows in x that would be retained if we were to merge x with y.
Conversely, the anti_join function returns rows of x that would not be retained if we were to merge with y
