The R package bigalgebra provides cutting-edge linear algebra functionality for use with both regular R matrices and with matrices from bigmemory. This package was developed by Mike with help from Bryan Lewis. Jay has been working on user-friendly interface starting with the "Arith" methods ("+", "-", etc...), and more functionality will follow. 32-bit/64-bit note: Because of the design internals of R, it is only distributed with 32-bit BLAS libraries. As a result, a standard build of bigalgebra will have functionality limited to objects with 2^31 -1 elements (about 2 billion), just like R. We're working on determining the friendliest procedure for supporting 64-bit libraries; feel free to contact us for more information. |
