Name: VERSO: an R package for the inference of viral evolution models
Description: Mutations that rapidly accumulate in viral genomes during
        a pandemic can be used to track the evolution of the virus and,
        accordingly, unravel the viral infection network. To this
        extent, sequencing samples of the virus can be employed to
        estimate models from genomic epidemiology and may serve, for
        instance, to estimate the proportion of undetected infected
        people by uncovering cryptic transmissions, as well as to
        predict likely trends in the number of infected, hospitalized,
        dead and recovered people. VERSO is an algorithmic framework
        that processes variants profiles from viral samples to produce
        phylogenetic models of viral evolution. The approach solves a
        Boolean Matrix Factorization problem with phylogenetic
        constraints, by maximizing a log-likelihood function. VERSO
        includes two separate and subsequent steps; in this package we
        provide an R implementation of VERSO STEP 1.
