builtins                package: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.
