Language objectsUp: The name of any R object is usually a symbol. Symbols can be created through the functions as.
Symbols have mode "name", storage mode "symbol", and type "symbol". They can be coerced to and from character strings using as. They naturally appear as atoms of parsed expressions, try e.
Function objectsPrevious: An expression contains one or more statements. A statement is a syntactically correct collection of tokens. Expression objects are special language objects which contain parsed but unevaluated R statements. The main difference is that an expression object can contain several such expressions.
Another more subtle difference is that objects of type "expression" are only evaluated when explicitly passed to eval, whereas other language objects may get evaluated in some unexpected cases. An expression object behaves much like a list and its components should be accessed in the same way as the components of a list.
NULL objectPrevious: Expression objectsUp: Functions or more precisely, function closures have three basic components: The argument list is a comma-separated list of arguments. The second form of argument is used to specify a default value for an argument.
This value will be used if the function is called without any value specified for that argument. It is generally used if the number of arguments is unknown or in cases where the arguments will be passed on to another function.
The body is a parsed R statement. It is usually a collection of statements in braces but it can be a single statement, a symbol or even a constant. Any symbols bound in that environment are captured and available to the function. It is possible to extract and manipulate the three parts of a closure object using formals, body, and environment constructs all three can also be used on the left hand side of assignments.
The last of these can be used to remove unwanted environment capture.
When a function is called, a new environment called the evaluation environment is created, whose enclosure see Environment objects is the environment from the function closure. This new environment is initially populated with the unevaluated arguments to the function; as evaluation proceeds, local variables are created within it.
There is also a facility for converting functions to and from list structures using as. These have been included to provide compatibility with S and their use is discouraged.
Builtin objects and special formsPrevious: Function objectsUp: It is used whenever there is a need to indicate or specify that an object is absent.Here is an assignment that calls for the student to evaluate something.
