These are developer-facing functions, useful for supporting new model types. Some models require one or more R packages to be fully attached to make predictions, and some require only that the namespace of one or more R packages is loaded.

Usage

attach_pkgs(pkgs)

load_pkgs(pkgs)

Arguments

pkgs

A character vector of package names to load or fully attach.

Value

An invisible TRUE.

Details

These two functions will attempt either to:

• fully attach or

the namespace of the pkgs vector of package names, preserving the current random seed.

To learn more about load vs. attach, read the "Dependencies" chapter of R Packages. For deploying a model, it is likely safer to fully attach needed packages but that comes with the risk of naming conflicts between packages.
