The grover package provides a web-based API framework for remote access to a mass spectrometry .raw data repository, implemented using the plumber R package. API functionality includes:

• File information retrieval including file size and creation dates.
• File transfer.
• Raw mass spectrometry data file conversion to .mzML format.
• Retrieval of sample information from .raw file headers.

The package functionality is platform independent with file conversion and sample information retrieval functionality available through use of the msconverteR and rawrr R packages.

The grover package can be installed from GitHub using the following:

remotes::install_github('jasenfinch/grover')

The package documentation can be browsed online at https://jasenfinch.github.io/grover/.
