Tags for managing the NAMESPACE

Description

Learn the full details in vignette('namespace').

Key tags:

• ⁠@export⁠: Export this function, method, generic, or class so it's available outside of the package.

• ⁠@exportS3Method ${1:package}::${2:generic}⁠: Export an S3 method. Only needed when the method is for a generic from a suggested package.

• ⁠@importFrom ${1:package} ${2:function}⁠: Import specific functions from a package.

• ⁠@useDynLib ${1:package}⁠: Import compiled code from another package.

Other less frequently used tags:

• ⁠@evalNamespace ${1:r-code}⁠: Evaluate arbitrary code in the package namespace and insert the results into the NAMESPACE. Should return a character vector of directives.

• ⁠@exportClass ${1:class}⁠: Export an S4 class. For expert use only; in most cases you should use ⁠@export⁠ so roxygen2 can automatically generate the correct directive.

• ⁠@exportMethod ${1:generic}⁠: Export S4 methods. For expert use only; in most cases you should use ⁠@export⁠ so roxygen2 can automatically generate the correct directive.

• ⁠@exportPattern ${1:pattern}⁠: Export all objects matching a regular expression.

• ⁠@import ${1:package}⁠: Import all functions from a package. Use with extreme care.

• ⁠@importClassesFrom ${1:package} ${2:class}⁠: Import S4 classes from another package.

• ⁠@importMethodsFrom ${1:package} ${2:generic}⁠: Import S4 methods from a package.

• ⁠@rawNamespace ${1:namespace directives}⁠: Insert literal text directly into the NAMESPACE.
