dotplot for enrichment result

This is a feature request from clusterProfiler user. It's similar to what I implemented in clusterProfiler for comparing biological themes. For comparing different enrichment results, the x-axis represent different gene clusters while for a single enrichment result, the x-axis can be gene count or gene ratio. This is actually similar to traditional barplot, with dot position as bar height...

BMC favors source code plagiarism

I found source code plagiarism a year ago and reported this case to BMC Systems Biology: I listed source code of many functions that are exactly copied from GOSemSim with only function name changed in my email. The detail of source code plagiarism can also be found at Proper use of GOSemSim. Read More: 9738...

use clusterProfiler as an universal enrichment analysis tool

clusterProfiler supports enrichment analysis of both hypergeometric test and gene set enrichment analysis. It internally support Gene Ontology analysis of about 20 species, Kyoto Encyclopedia of Genes and Genomes (KEGG) with all species that have annotation available in KEGG database, DAVID annotation, Disease Ontology and Network of Cancer Genes (via DOSE for human) and Reactome Pathway (via ReactomePA for...

using GOSemSim to rank proteins obtained by co-IP

Co-IP is usually used to identified interactions among specific proteins. It is widely used in detecting protein complex. Unfortunately, an identified protein may not be an interactor, and sometimes can be a background contaminant. Ranking proteins can help us to focus a study on a few high quality candidates for subsequent interaction investigation. My R package GOSemSim has been...
