[R-pkgs] ANN: 'weaver' package, caching for Sweave

Hi all,

I've added a new package 'weaver' to the BioC repository:


The weaver package provides extensions to the Sweave utilities
included in R's base package.  The focus of the extensions is on
caching computationally expensive (time consuming) code chunks in
Sweave documents.

Why would you want to cache code chunks?  If your Sweave document
includes one or more code chunks that take a long time to compute, you
may find it frustrating to make small changes to the document.  Each
run requires recomputing the "expensive" code chunks.  If these chunks
aren't changing, you can benefit from the caching provided by weaver.

To install:


If you give it a try and have any feedback, drop me a note.

Best Wishes,

+ seth
