base (version 3.3)

builtins: 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.

Value

A character vector.

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.
