R multidplyr: how to assign packages to clusters

Question

I am using the package multidplyr where you can split the data over multiple cores within a dplyr pipe. You can assign values and functions to the cores with cluster_assign_value(), but the question is how to assign packages to the clusters? Because it should be able to use packages within the functions.

I expect something like cluster_assign_package() but I cannot find such function.

Answer 1

You can also assign a package to the clusters with cluster_library()

Answer 2

Already found the answer: add library(packageName) in the function definition.
