THE BIGMEMORY PACKAGE:
MASSIVE DATA, SHARED MEMORY, AND CONCURRENT PROGRAMMING
Department of Statistics
Multi-gigabyte data sets challenge and frustrate R users even on well-equipped hardware. C/C ++ and Fortran programming can be helpful, but are cumbersome for interactive data analysis and lack the flexibility and power of proglangR's rich statistical programming environment. The package bigmemory bridges this gap, implementing massive matrices and supporting their basic manipulation and exploration. It is ideal for problems involving the analysis in R of manageable subsets of the data, or when an analysis is conducted mostly in C ++. The data structures may be allocated to shared memory with transparent read and write locking, allowing separate processes on the same computer to share access to a single copy of the data set. The data structures may also be file-backed, allowing users to more easily manage and analyze data sets larger than available RAM. These features of bigmemory open the door for powerful and memory-efficient parallel analyses and data mining of massive data sets. This talk will include applications in biomedical imaging and exploration of 2009 JSM Data Expo airline data.
