The S Documentation System
As described in Chapter 9 of Programming with Data,
online documentation in S uses S objects, kept in a special meta
Computations for online help are a combination of S computations on
these objects and other computations using a mapping of documentation
objects to the SGML language.
The advantage of this organization is that both the S and the SGML
versions of the documentation are capable of representing the
structure of the information.
The S side of the computations can map information from general S
objects into the documentation (for example, using objects that
represent S expressions), while the SGML side can organize both
structural information about the document (what information is allowed
and where) and also rendering information when web-based tools are
used to view the documentation.
The use of SGML allow users to exploit
the new XML technology currently being developed.
Among other benefits, we should see simpler and more productive
search methods operating on the documentation
and opportunities for research on more effective integrated help
