Description: PRC is a small \code{vegan}- and \code{LMMsolver}-based
        package to create and display Principal Response Curves (PRC)
        and smooth Principal Response Curves (PRC). PRC is a special
        case of Redundancy Analysis (rda) for multivariate responses in
        designed experiments and repeated measurement designs. PRC
        expresses ordination scores as deviation from a reference,
        usually to visualize multivariate A-dependent effects (e.g
        time-dependent effects) of a treatment B in (un)balanced
        factorial experiments. The main user functions are
        \code{\link{doPRC}}, \code{\link{plotPRC}},
        \code{\link{plotPRC2d}} and \code{\link{smoothPRC}}. The
        easiest example is the code demo \code{PRC_pyrifos}. This
        version includes smoothPRC (\code{\link{smoothPRC}} using
        \code{\link{set_smoothPRC_model}}).
