[R] Splitting Large Data Frame into Two

[Sarah Goslee]

How are you deciding which values in the first column go into which subset?

If you have a vector containing those values, you could use %in% or if
they're determined logically you could use that criterion.

A reproducible example and a bit more information would get you more
concrete answers.
