Hi all,

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

http://www.bioconductor.org/packages/1.9/bioc/html/weaver.html

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:

  source("http://bioconductor.org/biocLite.R")   biocLite("weaver")

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

Best Wishes,

+ seth
