For Linux users, it is probably installable through the distribution's package manager.
For others, the R language website: https://www.r-project.org
Also try the IDE from RStudio to make life more pleasant: https://www.rstudio.com
Good luck! It is a fun journey and a big, deep, wonderful, rewarding rabbit hole.

The R for Data Science book really is the best, but I would also recommend https://www.datacamp.com/ for some great video tutorials.
Also check out: R for Data Science: http://r4ds.had.co.nz/
It's got a lot of good intro materials for R. Though having some understanding of another programming language would be pretty helpful.
Where does one "get" R?
