aroma.affymetrix (version 1.6.0)
Analysis of large Affymetrix microarray data sets
Description
This package implements classes for files and sets of
files for various Affymetrix file formats, e.g.
AffymetrixCdfFile, AffymetrixCelFile, and AffymetrixCelSet.
These are designed to be memory efficient but still being fast.
The idea is to keep all data on file and only read data into
memory when needed. Clever caching mechanisms are used to
minimize the overhead of data IO. All of the above is hidden
in the package API and for the developer (and the end user),
the data is queried as if it lives in memory. With this design
it is only the diskspace that limits the number of arrays that
can be analyzed.
