Makes sure that the packages are loaded in slave process so that they can be used in a job function which is later run with parallelMap().

For all modes, the packages are also (potentially) loaded on the master.

parallelLibrary(
  ...,
  packages,
  master = TRUE,
  level = NA_character_,
  show.info = NA
)

Arguments

...

character
Names of packages to load.

packages

(character(1))
Names of packages to load. Alternative way to pass arguments.

master

(logical(1))
Load packages also on master for any mode? Default is TRUE.

level

(character(1))
If a (non-missing) level is specified in parallelStart(), the function only loads the packages if the level specified here matches. See parallelMap(). Useful if this function is used in a package. Default is NA.

show.info

(logical(1))
Verbose output on console? Can be used to override setting from options / parallelStart(). Default is NA which means no overriding.

Value

Nothing.
