SmartML is not the first AutoML package in R, as stated in the README

[ledell]

SmartML is the first R package to deal with the sueprvised machine learning automation, and it is built over 16 different classifier algorithms from different R packages.

This is incorrect. The h2o package was the first package in R to provide an AutoML algorithm. The h2o.automl() function was first released in the h2o package in 2017. It's also the most popular AutoML framework in R and has been shown to achieve state-of-the-art performance, as compared to the top AutoML systems. More information here.
