The 'cacher' package contains a set of routines for caching statistical 
analyses.  The idea is that an analysis stored in a file (say, 'foo.R') is run 
and the results of the evaluated expressions are cached in a database.  These 
cached results can subsequently be packaged up and distributed over the interweb.

I've just uploaded to CRAN version 0.1-2 of the 'cacher' package.

There is a brief document describing the package available at


Some sample cached analyses can be found at


For example, if you wanted to download the analysis associated with the 
'sample.R' file, you could run

clonecache(id = "44bf", all.files = TRUE)

Using the tools in the 'cacher' package you could then explore the data and code 
that make up this analysis.

This package is by no means 'complete' and is still evolving.  I would greatly 
appreciate any feedback or suggestions on the design if you end up using the 
package for any reason.
