I started working with R 2 1/2 years ago. I remember opening R closing it and thinking it was the dumbest thing ever (command line to a non programmer is not inviting). Now it’s my constant friend. From the beginning I took notes to remind myself all of the things I learned and relearned. They’ve been invaluable to me in learning.

There are likely bad or outdated practices in there but I figured they may be helpful to others learning the language and so I’m sharing.

Note that :

1) they are poorly arranged
2) they may have mistakes
3) they don’t credit others work properly or at all

They were for me but now I think maybe others will find them useful so here they are:
