Estimate, fit and compare Structural Equation Models (SEM) and network models (Gaussian Graphical Models; GGM) using OpenMx. Allows for two possible generalizations to include GGMs in SEM: GGMs can be used between latent variables (latent network modeling; LNM) or between residuals (residual network modeling; RNM). For details, see Epskamp, Rhemtulla and Borsboom (2017) <doi:10.1007/s11336-017-9557-x>.

Implements the letter value 'boxplot' which extends the
    standard 'boxplot' to deal with both larger and smaller number of data
    points by dynamically selecting the appropriate number of letter
    values to display.

Generates the Langa-Weir classification of cognitive function for
    the 2022 Health and Retirement Study (HRS) cognition data. It is
    particularly useful for researchers studying cognitive aging who wish to
    work with the most recent release of HRS data. The package provides
    user-friendly functions for data preprocessing, scoring, and classification
    allowing users to easily apply the Langa-Weir classification system.

Provides a flexible and easy-to use interface for the soil vegetation 
    atmosphere transport (SVAT) model LWF-BROOK90, written in Fortran.
    The model simulates daily transpiration, interception, soil and snow evaporation, 
    streamflow and soil water fluxes through a soil profile covered with vegetation, 
    as described in Hammel & Kennel (2001, ISBN:978-3-933506-16-0) and Federer et al. (2003) 
    <doi:10.1175/1525-7541(2003)004%3C1276:SOAETS%3E2.0.CO;2>. A set of high-level functions
    for model set up, execution and parallelization provides easy access to plot-level SVAT 
    simulations, as well as multi-run and large-scale applications.
