MSnbase is an R/Bioconductor package that provides infrastructure for plotting, data manipulation and processing mass spectrometry and proteomics data. The project was started by Laurent Gatto in October 2010 (Mon Oct 4 23:35:23 2010, according to the git log) and has, since then, benefited from various contributions.

The official page is the Bioconductor landing page (release or devel versions). The github page page is for sharing, testing, issue tracking and forking/pulling purposes. The Bioconductor svn server, is the official repository for the working source code.
