You may want to look at the SQLiteDF package, this allows you to put your data into an SQLite database and treat that like a normal vector or data frame inside of R.

Could it be possible to implement an a new data type in R, like a vector, but instead holding the information in memory, the data lies on an file. If data is accessed, the data type vector get the information automatically from the file. There is a package out there (named ff) but the accessed boundary have to be declared by the user this is a disadvantage. Greetings.
