Parallel R - E-book - Multi-format

It's tough to argue with R as a high-quality, cross-platform, open source statistical software product-unless you're in the business of crunching Big Data. This concise book introduces you to several strategies for using R to analyze large datasets. You'll learn the basics of Snow, Multicore, Parallel, and some Hadoop-related tools, including how to find them, how to use them, when they work well, and when they don't. With these packages, you can overcome R's single-threaded nature by spreading work across multiple CPUs, or offloading work to multiple machines to address R's memory barrier. - Snow: works well in a traditional cluster environment - Multicore: popular for multiprocessor and multicore computers - Parallel: part of the upcoming R 2.14.0 release - R+Hadoop: provides low-level access to a popular form of cluster computing - RHIPE: uses Hadoop's power with R's language and interactive shell - Segue: lets you use Elastic MapReduce as a backend for lapply-style operations
