Not sure how versed you are in R, supposing you currently dabble, this is a good way to get you wrangling like it's going outta style: https://r4ds.had.co.nz/
Language isn't really important here; what's important is tooling, and R definitely has the tooling. I would look at this benchmark reference for database-like operations, and you'll see that data.table (a very fast and memory-efficient R package) consistently ranks as one of the fastest tools out there that can also support a wide range of memory loads.
