Apologies if this is not the right place to ask the question.
My son (& myself) are completely new to RStudio but as part of his last 2ndry school exams (17 yr old), there is a Rstudio module. He is not understanding the platform, and I suspect the teaching isn't great as it's their first year offering the stats course. There seems to be plenty of online tutorials but not sure which are best for complete novices, but are there papers, or indeed does anyone offer 121 online tutorials? Apologies if this is not the right forum for this question
Probably the standard recommendation is Hadley Wickham's R for Data Science .
Another book that looks to have a very good intro the basic "mechanics" of setting up and using R is David Kane's Preceptor’s Primer for Bayesian Data Science. It's not really intended as an introduction to R as you can see from the title but if you read through the first two or three chapters he gives a lot of code that can be readily adapted to your needs. He does not presume any pre-knowledge of R nor of programming in general as far as I can see and he is discussing some basic stats there as well.
