The R package bigstatsr provides functions for fast statistical analysis of large-scale data encoded as matrices. The package can handle matrices that are too large to fit in memory thanks to memory-mapping to binary files on disk. This is very similar to the format big.matrix provided by the R package bigmemory, which is no longer used by this package.
