FlashR is an R package that accelerate the existing R matrix functions to process tera-scale datasets at the lightning speed. FlashR overrides many R matrix functions in the R "base" package so that users can execute many existing R code in FlashR with no or little modification. FlashR parallelizes all matrix operations automatically and scales to large datasets by storing matrices on solid-state drives (SSDs). It executes many matrix operations together to achieve performance comparable to optimized C implementations.
