This post is heavily based from the dplyr Cheatsheet link and the online resource. There are other good resources for R that I have used.
For now I am using R to sharpen my skills in programming and getting into AI/machine learning. I do hope to transition into Python soon. (I come from a math/stats background focused on stochastic calculus for finance and simulations. )
About the group, I've should've worded it better. The group referred to a few individual Steemians who have been posting educational content in the fields of math, programming, science, education and the like. There is no official group nor I am part of one.
