the elements of a list do not have to be of the same type.List elements are accessed through three different indexing operations. Lists are vectors, and the basic vector types are referred to as contains one or more statements.An expression object behaves much like a list and its components should be accessed in the same way as the components of a list.

There are also many functions available to perform explicit coercion. R has six basic (‘atomic’) vector types: logical, integer, real, complex, string (or character) and raw.

When programming in the R language the type of an object generally doesn’t affect the computations, however, when dealing with foreign languages or the operating system it is often necessary to ensure that an object is of the correct type. The modes and storage modes for the different vector types are listed in the following table.

It provides, among other things, a programming language, high level graphics, interfaces to other languages and debugging facilities. The R language is a dialect of S which was designed in the 1980s and has been in widespread use in the statistical community since. Chambers, was awarded the 1998 ACM Software Systems Award for S.

The language syntax has a superficial similarity with C, but the semantics are of the FPL (functional programming language) variety with stronger affinities with Lisp and .

In R, however, the symbols are themselves objects and can be manipulated in the same way as any other object.

This is different from many other languages and has wide ranging effects.

The main difference is that an expression object can contain several such expressions.

Another more subtle difference is that objects of type , whereas other language objects may get evaluated in some unexpected cases.

Many of these become natural once one is familiar with the underlying concepts.

In some cases, there are multiple ways of performing a task, but some of the techniques will rely on the language implementation, and others work at a higher level of abstraction.
