[R] integer and floating-point storage

I note that current implementations of R use 32-bit integers for integer vectors, but I am working with large arrays that contain integers from 0 to 3, so they could be stored as unsigned 8-bit integers. Can R do this? (FYI -- This is for storing minor-allele counts for genetic studies. There
