R: Returns the Names of All Built-in Objects

builtins {base} | R Documentation

## Returns the Names of All Built-in Objects

### Description

Return the names of all the built-in objects. These are fetched directly from the symbol table of the R interpreter.

### Usage

    builtins(internal = FALSE)

### Arguments

`internal` | a logical indicating whether only ‘internal’ functions (which can be called via `.Internal`) should be returned.

### Details

`builtins()` returns an unsorted list of the objects in the symbol table, that is all the objects in the base environment. These are the built-in objects plus any that have been added subsequently when the base package was loaded. It is less confusing to use `ls(baseenv(), all=TRUE)`.

`builtins(TRUE)` returns an unsorted list of the names of internal functions, that is those which can be accessed as `.Internal(foo(args ...))` for foo in the list.

### Value

A character vector.
