Bioconductor
• R software project for the analysis and
comprehension of biomedical and genomic data.
– Gene expression arrays (cDNA, Affymetrix)
– Pathway graphs
– Genome sequence data
• Started in 2001 by Robert Gentleman, Dana
Farber Cancer Institute.
• About 25 core developers, at various institutions
in the US and Europe.
• Tools for integrating biological metadata from the
web (annotation, literature) in the analysis of
experimental metadata.
• End-user and developer packages.

結論
1.Bioconductor is a useful tool in dealing
with static problem on microarray
2.affy example show the power of the R
3. I benefit a lots from this report like how to
use bioC in R.
