6 data.table

data.table is Alec’s favorite R package because it is incredibly efficient, lightweight and has incredibly responsive and dedicated developers (thank you!). dplyr and etc tidyverse packages are full of great functions and workflows, so check those out as well. Life isn’t about strange, strict binaries/camps - use what works for you.

Note: if you are having install issues on Mac, check out this reference can be really useful.
