Package: ume Title: Ultrahigh-Resolution Mass Spectrometry Data Evaluation for Complex Organic Matter Version: 1.6.1 Authors@R: c( person("Boris", "Koch", email = "boris.koch@awi.de", role = c("aut", "cre"), comment = c(ORCID = "0000-0002-8453-731X")), person("Stephan", "Frickenhaus", role = "ctb", comment = c(ORCID = "0000-0002-0356-9791")), person("Oliver", "Lechtenfeld", role = "ctb", comment = c(ORCID = "0000-0001-5313-6014")), person("Tim", "Leefmann", role = "ctb", comment = c(ORCID = "0000-0002-5784-8657")), person("Fabian", "Moye", role = "ctb", comment = c(ORCID = "0000-0002-4632-5033")) ) Description: Provides tools for assigning molecular formulas from exact masses obtained by ultrahigh-resolution mass spectrometry. The methodology follows the workflow described in Leefmann et al. (2019) . The package supports the inspection, filtering and visualization of molecular formula data and includes utilities for calculating common molecular parameters (e.g., double bond equivalents, DBE). A graphical user interface is available via the 'shiny'-based 'ume' application.
