The avalanche of publications mentioning GO

Gene Ontology is the de facto standard for annotation of gene products. It has been widely used in biological data mining, and I believe it will play more central role in the future. Publications mentioning GO was collected and deposited in GO ftp, and can be accessed (ftp://ftp.geneontology.org/go/doc/). Read More: 454 Words Totally

GOSemSim redesign in terms of S4 classes

November 30, 2010
By

I started to develop GOSemSim package two years ago when I was not quite familiar with R. I am very happy to see that someone use it and found it helpful. I try to learn S4 and redesign GOSemSim with S4 classes and methods in the pass two weeks, and the very first version was implemented. As I’m...

The S3 OOP system

October 15, 2010
By

R currently supports two internal OOP systems (S3 and S4), and several others as add-on packages, such as R.oo, and OOP. S3 is easy to use but not reliable enough for large software projects. The emphasis of the S3 system was on generic functions and polymorphism. It’s a function centric system which is different to class centric system like...

ClusterProfiles

It is very common to cluster genes based on their expression profiles, and also very common to integrate Gene Ontology to observe the distribution of biological processes, molecular functions and cellular components for a given gene list. But, what if the two in combination? The Gene Ontology distributions across a variety of gene clusters may give us a...
