[R-pkgs] SOAR - Stored object caches for R

I have just submitted SOAR version 0.99-2 to CRAN.  This replaces version 0.99-1, submitted yesterday, in which a small bug was discovered rather quickly (only affecting Windows, though).

This package is a small set of utilities for making and managing 'Stored Object Caches' for R.  These allow objects to be stored on the disc rather than in memory, with automatic recall into R by the delayedAssign mechanism.  It uses the same basic idea as the package g.data of David Brahm, though the usage is rather different.

There are two main purposes: large objects can easily be managed so as not to overload memory, and frequently used functions and datasets can easily be made accessible to different R sessions.  The effect is somewhat like that of the use of the .Data directory in S-PLUS, (a program not unlike R), though somewhat more manually driven.

There is a vignette, "SOAR", which prospective users may care to read first for a more complete discussion.

This package is the formal successor to an older package, ASOR, which was never released on CRAN.  Users of the ASOR package may wish to look first at Appendix C of the vignette, which lists the important differences.  The transition from ASOR to SOAR, though, should be almost transparent.
