If any other specs are needed let me know. > "data sets are very large’ - well, the machines listed below are certainly not suitable to run anything on large data ;) so you may want to quantify what you mean here. You want as much RAM as possible for large data since that is the single item that will cause huge drop-off in performance when exhausted and R certainly can take quite a bit of memory if this is really your only machine to run computing on. Note that in modern Apple laptops you cannot add more memory later, so this is rather important factor. Given a choice of the two MacBook Air is not a computing machine - it’s optimized for power consumption, not speed, so the only reason to go for it is if you’re looking for a light notebook and don’t care about the computing speed as much.
