The set of R functions that come with a basic installation of R, before you add external packages
Joins that act like the dplyr::filter() function in that they remove rows from the data in one table based on the values in another table.
Joins that bind one table to another by adding their rows or columns together.
Functions that compare two tables and return rows that match (intersect), are in either table (union), or are in one table but not the other (setdiff).
Joins that act like the dplyr::mutate() function in that they add new columns to one table based on values in another table.
The end!
