Saving objects in a datastore makes it very easy to pass arguments to, and reference R objects with, embedded R execution functions. You can save objects that you create in one R session in a single datastore in the database. You can pass the name of this datastore to an embedded R function as an argument for loading within that function. You can use a datastore to easily pass one object or multiple objects.
