Hi, Hmm, why didn't you just post a URL? Incidentally I am actually very interested in seeing your code. I am working on a project where the data set is extremely large, but the permuntation of the states of the data is extremely small. Each piece of data consists of only 4 states, so stuffing it as an R object (which takes up 32-byte? on 32-bit machines) or even an char vector is quite wasteful; so I have written a "strange" data.frame where internally it uses only 2-bit for storage. (it is still work-in-process but I have got to the point of being able to get and set each 2-bit cell now).
