The MSnbase package

MSnbase is an R/Bioconductor package that provides infrastructure for plotting, 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, in particular Sebastian Gibb and Johannes Rainer.

The official page is the Bioconductor landing page (release or devel versions). The github page page is for active development, issue tracking and forking/pulling purposes.

To get an overview of the package, see the MSnbase-demo vignette. More vignettes are available in the Articles tab.
