DF.to.longDT

A <code>data.frame</code> or <code>data.table</code> in wide format

df_wide

<code>TRUE</code> (default) to return a <code>data.frame</code>, <code>FALSE</code> returns a <code>data.table</code>

return_DF

Faster utility function for converting wide-format <code>data.frame</code> into a long format.
Internally uses <pkg>data.table</pkg> package functions <code>melt.data.table</code> and <code>dcast.data.table</code>.

A flexible tool for simulating complex longitudinal data using
    structural equations, with emphasis on problems in causal inference.
    Specify interventions and simulate from intervened data generating
    distributions. Define and evaluate treatment-specific means, the average
    treatment effects and coefficients from working marginal structural models.
    User interface designed to facilitate the conduct of transparent and
    reproducible simulation studies, and allows concise expression of complex
    functional dependencies for a large number of time-varying nodes. See the
    package vignette for more information, documentation and examples.
