Description: We rewrite of RAMpath software developed by John McArdle
        and Steven Boker as an R package. In addition to performing
        regular SEM analysis through the R package lavaan, RAMpath has
        unique features.  First, it can generate path diagrams
        according to a given model. Second, it can display path tracing
        rules through path diagrams and decompose total effects into
        their respective direct and indirect effects as well as
        decompose variance and covariance into individual bridges.
        Furthermore, RAMpath can fit dynamic system models
        automatically based on latent change scores and generate vector
        field plots based upon results obtained from a bivariate
        dynamic system. Starting version 0.4, RAMpath can conduct power
        analysis for both univariate and bivariate latent change score
        models.
