The oem package has been on CRAN for some time now, but with the latest update I expect few structural changes to the user interface. oem is a package for the estimation of various penalized regression models using the oem algorithm of Xiong et al. (2016). The focus of oem is to provide high performance computation for big tall...

Fast and Big Linear Model Fitting with bigmemory and RcppEigen

July 6, 2016
By

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 linear models using data...

Linking bigmemory and RcppEigen

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 Dirk Eddelbuettel. If bigmemory...

This post is mostly an attempt to familiarize myself with Rmarkdown, jekyll, and github. I recently posted an R package (rfunctions), which contains some functions I wrote (or modified) that make my life a little easier. I’ll go through some examples in R to highlight the various functions included. Installation rfunctions is not available on CRAN, but can be installed using...
