This is a reposting, the time and room have been changed. ----------------- Topic: The New S Language Speaker: John Chambers Statistics and Data Analysis Group AT&T Bell Laboratories Murray Hill, New Jersey Date: Friday, October 28, 1988, 4:00 p.m. Place: Sidney Smith Hall, room 1074, 100 St George St, University of Toronto 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. ---------------------- Coffee and tea will be served in the Delury Lounge (SS6006) at 3:30 p.m.
