R packages are much easier to explore if finding and writing each function is done for you. GUIs presented here do that. Just fill out a PnC dialogue and they generate R code. This is helpful for beginners, lazy and forgetful experts too. These do EDA, stats and viz but not real ML. Bottom 4 can be automatically run and installed from R script at end of this page.

I liked trying out everything on my current fave dataset. I really wish I had explored these options as I was starting out because they would have saved me months of work. R studio notebooks are great too but they are better for depth not breadth.
