## Internal Versions of the Foreign Function Interface

### Description

Internal versions of `.Call` and `.External`.

### Usage

        .Call.graphics(.NAME, ..., PACKAGE)
    .External.graphics(.NAME, ..., PACKAGE)

### Arguments

`...` | arguments to be passed to the foreign function.
`PACKAGE` | see the corresponding argument of `.Call`.

### Details

The `.graphics` versions of `.Call` and `.External` are used when calling code which makes low-level graphics calls. They take additional steps to ensure that the device driver display lists are updated correctly.

Currently `.Call.graphics` is used in package grid and `.External.graphics` is unused.

These are primitive functions.

An R object.
