How to increase RAM to finish capstone project

Hi all,

I am working on a capstone for a certificate program and I can't even read two out of my 12 csv files without crashing R because the RAm goes through the roof. Is there a way to get me through this project without paying $100 to increase the RAM? I don't have the resources to make a purchase like that right now, but I also can't finish my course with R the way it is...any help is appreciated!

Do the csv's have extraneous data that you could dispense with ? i.e. you could stream them in, dropping what you dont need as you go and perhaps what is left is small enough to fit in your memory?
readr has read_csv_chunked for that sort of thing.
also disk.frame exists for doing dplyr work on bigger than memory data, it might get you part way where you need to go.
