Abstract:
S is an interactive language and system for graphics, data analysis and
quantitative computing that has been in use at universities, and in industry
since 1984.  A new version of S has just been written, retaining the best
features of the previous versions but incorporating a number of new features,
such as dynamically defined functions and direct interfaces to UNIX, Fortran
and C.

New S is a unified language that does away with the old macro processor
and interface language.  It performs computations in double precision, and
has a complex data type.  It includes graphics objects to represent plots,
programming support tools, the use of the language as data, and a formal 
semantic model that lets user functions have extensive control over evaluation.

The recent changes have enhanced S as a tool for data analysis and have also
made it more suitable for implementing substantial applications.  A book,
"The New S Language", describes in detail how to use S.  This talk describes
some of the ideas behind new S and shows how it can be used in data analysis and
programming, illustrating along the way the changes from old S.
