July 6, 2016

In a previous post, I went over the basics of linking up bigmemory and the eigen C++ library via RcppEigen. In this post I’ll take this a bit further by creating a version of the fastLm() function of RcppEigen that can accept bigmemory objects. By doing so, we will create a fast way to fit...

June 3, 2016

The bigmemory package offers a set of tools for R which allow for manipulation larger-than-memory objects within R. It has some basic functions but is certainly not comprehensive. The eigen C++ linear algebra library is a highly efficient numerical linear algebra library and can be interfaced to R through RcppEigen by Douglas Bates and...
