Hi wonderful rstudio community!
I'm considering learning more about C++ as a means to better understand Rcpp and its subsequent use in R. I'd like to know what happens 'under the hood' in packages like dplyr and see a lot of benefit to knowing C++ to tackle the computationally heavy things that R doesn't need to do, e.g., RcppEigen.
Any thoughts from those who have gone down this road already? Tips? Resources?
I will likely rely heavily on this: http://pythontutor.com/cpp.html#mode=edit
It was really helpful when I was learning Python (wish there was an equivalent in R)

Edit: 
I also received this as a resource for learning for C++
I also found and may use this as a reference as well
