RaMS: R Access to Mass-Spec Data

Description

R-based access to mass-spectrometry (MS) data. While many packages exist to process MS data, many of these make it difficult to access the underlying mass-to-charge ratio (m/z), intensity, and retention time of the files themselves. This package is designed to format MS data in a tidy fashion and allows the user perform the plotting and analysis.

Details

The main function of RaMS is grabMSdata(), which handles most use-cases and automatically detects file types and is vectorized over multiple files. If more control over the file reading is desired, both grabMzmlData() and grabMzxmlData() have been exposed to the user, and grabAccessionData() is available if a specific accession value from an mzML file is desired.

Other useful functions in the package include minifyMSdata() and tmzmlMaker() which have their own documentation pages and vignettes. Two small helper functions are also included, pmppm() and between() (with the alias ⁠%between%⁠) imported from data.table.
