[![](]( [![R-CMD-check-bioc](]( # The `MSnbase` package <img align = "right" src="" height="200"> [**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 package 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. ## The R for Mass Spectrometry initiative The aim of the *R for Mass Spectrometry* initiative is to provide efficient, thoroughly documented, tested and flexible R software for the analysis and interpretation of high throughput mass spectrometry assays, including proteomics and metabolomics experiments. The project formalises the longtime collaborative development efforts of its core members under the R for Mass Spectrometry organisation to facilitate dissemination and accessibility of their work. If you are using MSnbase, consider switching to the **R for Mass Spectrometry** packages, in particular, [Spectra]( for raw data, [PSMatch]( for identification data, and [QFeatures]( for quantitative data. See for details. ## Installation To install the package: ```r install.packages("BiocManager") BiocManager::install("MSnbase") ``` If you need the github version (not recommended unless you know what you are doing), use ```r BiocManager::install("lgatto/MSnbase") ``` ## Questions General questions should be asked on the [Bioconductor support forum](, using `MSnbase` to tag the question. Feel also free to open a GitHub [issue](, in particular for bug reports. ## Citation To cite the `MSnbase` package in publications, please use: > Gatto L, Lilley KS. *`MSnbase` - an R/Bioconductor package for > isobaric tagged mass spectrometry data visualization, processing and > quantitation*.

If you want to contribute to this package, you should follow the same conventions as the rest of the functions. Please do get in touch (preferable opening a [github issue]( to discuss any suggestions. The [`MSnbase` development vignette]( gives some background on the class infrastructure.
