Can I specify certain bits a integer taken in R?

Question

I have a bunch of numbers to load into R for further anaysis. The numbers are small, <128. But there're 4G of such numbers. I would like to load them into a vector. Could I specify certain bits a integer taken in R to reduce memory usage? Breaking down the data was the only choice?

Answer 1

The ff CRAN package allows you to create vectors with 2,4,8,16 and 32 bit integers (signed or unsigned).
