Package "bigmemory" is now available on CRAN. A brief abstract follows:

Multi-gigabyte data sets challenge and frustrate R users even on well-equipped hardware.
C/C++ and Fortran programming can be helpful, but is cumbersome for interactive data analysis and lacks the flexibility and power of R's rich statistical programming environment.
The new package bigmemory bridges this gap, implementing massive matrices in memory (managed in R but implemented in C++) 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++. In a Unix environment,
the data structure 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. This opens the door for more powerful parallel analyses and
data mining of massive data sets.
