Abstract:
|
The S language was originally designed to analyze data that fits into memory. The bigdata package for S-PLUS introduces a system for working with arbitrarily large data sets. We describe the design of the bigdata objects and its chunking mechanism for data access. The basic S classes and methods for bigdata objects will be presented as well as some of graphical and statistical modeling methods that use bigdata. We show how to extend the methods and discuss the limitations that we have encountered.
