getPackageName {methods}R Documentation

The Name associated with a Given Package

Description

The functions below produce the package associated with a particular environment or position on the search list, or of the package containing a particular function. They are primarily used to support computations that need to differentiate objects on multiple packages.

Usage

getPackageName(where)

packageSlot(object)
packageSlot(object) <- value

Arguments

where the environment or position on the search list associated with the desired package.
object object providing a character string name, plus the package in which this object is to be found.
value the name of the package.

Details

Package names are normally installed during loading of the package, by the INSTALL script or by the library function. (Currently, the name is stored as the object .packageName but don't trust this for the future.)

Value

packageName return the character-string name of the package (without the extraneous "package:" found in the search list).
packageSlot returns or sets the package name slot (currently an attribute, not a formal slot, but this will likely change).

Examples

## both the following usually return "base"
getPackageName(length(search()))
