DirectEffects is an R package to estimate controlled direct effects. As of now, the only model supported is sequential g-estimation, but we plan to expand to other models, including doubly robust estimators, in the future. For more information on how CDEs can be useful for applied research and a brief introduction to sequential g-estimation, see our 2016 APSR. Note that this package is still in alpha stages and is under rapid development.
