Not an R tutorial
So you want to learn R? Well, there's lots of resources for
learning R on the internet. But perhaps too much, so unless you
have a specific question or a specific error message you can
enter into the search engine, you can spend a lot of time
searching for needles in haystacks.|
I've just been using Google to find basic information about key concepts in R, and found it difficult to find good sources. Many of the pages go into unnecessary detail, assume a background in programming in other languages, or use abstruse examples.
So some recommendations seem to be in order.
In general, I found YouTube videos to be more appropriate for R beginners than most web pages. The videos from DataCamp are particularly impressive, being conceptually clear and professional. Maybe I should just recommend folks sign up for DataCamp, but I haven't looked at their actual courses.
The following are just some of the best links I came across during a few hours with Google. Let me know if you have your own suggestions: stats[dot]bcss[at]gmail[dot]com.
