browseSpectra: Browse spectra in a Spectra object

In rformassspectrometry/SpectraVis: Visualising and Exploring Spectra Data

Browse spectra in a Spectra object

Description

The browseSpectra() function opens a simple shiny application that allows to browse trough the individual scans of a Spectra object. The title of the scans contains the MS level, the retention time, if available the precursor m/z and precursor charge and a peptides sequence (as defined in the sequence spectra variable) and the index of the scan. If a scans has a sequence (as defined in the sequence spectra variable), the matching fragments (as defined by PSMatch::calculateFragments() are labelled, otherwise the most intense peaks (as defined as those that have an intensity as high as half the highest peak) are labelled with their m/z.

See ?SpectraVis for an example.
