Description: Correspondence analysis (CA) is a matrix factorization
        method, and is similar to principal components analysis (PCA).
        Whereas PCA is designed for application to continuous,
        approximately normally distributed data, CA is appropriate for
        non-negative, count-based data that are in the same additive
        scale. The corral package implements CA for dimensionality
        reduction of a single matrix of single-cell data, as well as a
        multi-table adaptation of CA that leverages data-optimized
        scaling to align data generated from different sequencing
        platforms by projecting into a shared latent space. corral
        utilizes sparse matrices and a fast implementation of SVD, and
        can be called directly on Bioconductor objects (e.g.,
        SingleCellExperiment) for easy pipeline integration. The
        package also includes additional options, including variations
        of CA to address overdispersion in count data (e.g.,
        Freeman-Tukey chi-squared residual), as well as the option to
        apply CA-style processing to continuous data (e.g., proteomic
        TOF intensities) with the Hellinger distance adaptation of CA.
