Use Packages
Description
Use packages in R scripts by loading their namespace and attaching a package environment including (a subset of) their exports to the search path.
Usage
use(package, include.only)
Arguments
package |
a character string given the name of a package. |
include.only |
character vector of names of objects to include in the attached environment frame. If missing, all exports are included. |
Details
This is a simple wrapper around library which always
uses attach.required = FALSE, so that packages listed in the
Depends clause of the DESCRIPTION file of the package to
be used never get attached automatically to the search path.
This therefore allows to write R scripts with full control over what
gets found on the search path. In addition, such scripts can easily
be integrated as package code, replacing the calls to use by
the corresponding ImportFrom directives in ‘NAMESPACE’
files.
Value
(invisibly) a logical indicating whether the package to be used is available.
Note
This functionality is still experimental: interfaces may change in future versions.
