R is an excellent statistical tool. However its important data objects are memory objects: all processing in R takes place in memory.

ff is a R package for working with vectors that are bigger than memory, but lacks at the moment some standard statistical methods. The intention of ffbase is to provide the basic statistical functions for ff objects, so programming with ff will be easier.

To install ffbase from CRAN:

install.packages("ffbase")

To install the latest version from github

library(devtools)
install_github("edwindj/ffbase", subdir="pkg")
