Title: Using Bioconductor to Analyze your 23andme Data
Bioconductor is one of the open source projects of which I am most
fond. The documentation is excellent, the community wonderful, the
development fast-paced, and the software *very* well written.
There's a new package in the development branch (due to be released as
2.10 very soon) called `gwascat`. `gwascat` is a package that serves
as an interface to the [NHGRI's]( database of
genome-wide association studies.

For every minute you are angry, you lose sixty seconds of happiness. ::: unknown
Anger is a momentary madness, so control your passion or it will control you. ::: Horace Walpole
When angry, count ten before you speak; if very angry, a hundred. ::: Jefferson
Anger is a wind which blows out the lamp of the mind. ::: Robert G. Ingersoll
Holding on to anger is like grasping a hot coal with the intent of throwing it at someone else; you are the one getting burned. ::: Buddha
The best remedy for a short temper is a long walk. ::: Jacqueline Schiff
