Allows for multiple group item response theory alignment a la 'Mplus' to be applied to lists of single-group models estimated in 'lavaan' or 'mirt'. Allows item sets that are overlapping but not identical, facilitating alignment in secondary data analysis where not all items may be shared across assessments.

A lightweight, dependency-free toolbox for pre-processing XY
    data from experimental methods (i.e. any signal that can be measured
    along a continuous variable). This package provides methods for
    baseline estimation and correction, smoothing, normalization,
    integration and peaks detection. Baseline correction methods includes
    polynomial fitting as described in Lieber and Mahadevan-Jansen (2003)

Acknowledge all contributors to a project via a single
    function call. The function appends to a 'README' or other specified
    file(s) a table with names of all individuals who contributed via code
    or repository issues.  The package also includes several additional
    functions to extract and quantify contributions to any repository.

Tools to simulate alphanumeric alleles, impute genetic missing data and reconstruct non-recombinant haplotypes from pedigree databases in a deterministic way. Allelic simulations can be implemented taking into account many factors (such as number of families, markers, alleles per marker,
    probability and proportion of missing genotypes, recombination rate, etc).
    Genotype imputation can be used with simulated datasets or real databases (previously loaded in .ped format). Haplotype reconstruction can be carried
    out even with missing data, since the program firstly imputes each family genotype (without a reference panel), to later reconstruct the corresponding
    haplotypes for each family member. All this considering that each individual (due to meiosis) should unequivocally have two alleles per marker (one inherited
    from each parent) and thus imputation and reconstruction results can be deterministically calculated.
