The following functions to access/set the options from the set are assigned in envir:

setupPackageOptions(
  ...,
  NAME = NULL,
  ENVIR = topenv(parent.frame()),
  RESET = isLoadingNamespace()
)

Arguments

...

a single named list or named arguments that provide the default options and their values.

NAME

name of the set of options. This is used as a prefix for the name of the associated global option: package:<name>.

ENVIR

environment where the option wrapper functions will be defined. No function is defined if ENVIR=NULL

RESET

a logical that indicates whether the option set should overwrite one that already exists if necessary. The default is FALSE (i.e. no reset), except when loading a namespace, either from an installed package or a development package -- with devtools. If FALSE, an error is thrown if trying to setup options with the same name.
