We are pleased to announce the release of Bioconductor 2.2. This
release includes 35 new packages, and many improvements to existing
packages. There are now 260 package in Bioconductor 2.2. These
packages are compatible with R 2.7.0.
IMPORTANT: MAC OS USERS: the 'binary' builds currently available with
biocLite are not suitable for Tiger (OS X 10.4). We expect to have
Tiger-compatible builds within the next week. If you are using Tiger,
please refrain from migrating to R-2.7.0 until these binaries become
available, or use the 'type="source"' option to biocLite.
As a member of the Bioconductor community, you have contributed
greatly to this release. Perhaps you are a perplexed newcomer asking
for help on the Bioc mailing list. Perhaps you are an experienced user
seeking reproducible and advanced functionality. Or perhaps you are a
package developer helping others to make sound sense of their
data. Whatever your role, you've made Bioconductor the resource it is
today. We are especially grateful to package developers, to members of
the Bioconductor team in Seattle, and to those participants on the
Bioc mailing list who knowledgeably and patiently answer questions
large and small.
High-throughput genomic research is a dynamic and exciting field. It
is hard to predict what surprising packages are in store for future
Bioconductor releases. We anticipate continued integration with
diverse data sources, use of R's advanced graphics abilities, and
implementation of cutting edge research algorithms for the benefit of
all Bioconductor users. Short-read DNA resequencing technologies are
one area where growth seems almost certain.
We look forward to a vibrant release cycle!

Structured Analysis of Microarray Data
Packages still present in the 'development' branch, but no longer in
the release, include BeadExplorer, GeneRfold, MCRestimate, and
SAGElyzer. Packages retired from Bioconductor include arrayMagic,
ChromoViz, GeneTS, iSNetwork, iSPlot, and RMAPPER.
Significant Changes to Annotation Packages
Bioconductor 2.2 includes a large number of annotation
packages. Descriptions are available here:
New 'db' annotation packages replace their predecessors, e.g.,
hgu95av2.db replaces hgu95av2 . Both 'db' and original packages are
available in this release, but we anticipate that future releases will
only contain 'db' packages. Most db packages now contain Ensembl
New 'organism' packages are available for several model organisms: human,
org.Hs.eg.db; mouse, org.Mm.eg.db; rat, org.Rn.eg.db; yeast,
org.Sc.sgd.db; fly, org.Dm.eg.db; malaria, org.Pf.plasmo.db. Many of
these packages contain additional organism-specific annotations, e.g.,
flybase (Drosophila) or Jackson Laboratories (mouse) IDs.
New 'homology' packages summarize InParanoid homology data. Use these
and the organism packages to map between InParanoid and other IDS
IDs. Available homology packages include: human, hom.Hs.inp.db; mouse,
hom.Mm.inp.db; rat, hom.Rn.inp.db; yeast, hom.Sc.inp.db; fly,
The PFAM package is available as PFAM.db
Custom CDF packages provided by Manhong Dai are not currently
available, but should be shortly.
