请仔细描述一下哈,不然不知道.容易胡乱下

What are R and S-PLUS?
• R is a free implementation of a dialect of the S language,
the statistics and graphics environment for which John
Chambers won the ACM Software Systems award. S
was consciously designed to blur the distinction between
users and programmers. S-PLUS is a commercial system
(Insightful Co) based on Bell Labs’ S.
• S is a system for interactive data analysis. It has always been
designed with interactive use in mind.
• S is a high-level programming language, with similarities
to Scheme and Python. It is a good system for rapid
development of statistical applications. For example, the
survey package was developed by one person, part time, and
is about 1.5% the size of the Census Bureau’s VPLX package
(which does less).

Outline
• Reading data
• Simple data summaries
• Graphics
• Scripts, Transcripts, ESS.
• Stratified data summaries
• Sweave
• More on functions (example: bootstrap)
• Debugging and optimization
• A little on objects
• Regression models: lm, glm, coxph
• Packages
