EARL Boston Revisited

After a successful EARL London in September of this year (see here and here) it was Boston’s turn to shine. This is only the second time this conference has run, yet its quality of speakers is at par with London. This year’s edition welcomed twenty presenters from eight industries and saw almost a hundred attendees, yet another showcase for R’s widespread adoption across all industries. One of our fantastic keynotes at EARL Boston this year was Jenny Bryan, who has recently joined the RStudio team. Jenny used a series of visual analogies, which cleverly (and comically) combined Lego structures with Game of Thrones references to simplify data wrangling techniques. She also demonstrated to us the ‘map’ function from the purr package.  She successfully managed to convert me from an ‘apply’ user, armed with nothing more than Lego men, with…

miniCRAN – developing internal CRAN Repositories

by Steph Locke Today, I needed to work on a package that had numerous dependencies on internal packages and ones from CRAN. To be able to handle dependencies in the installation process, I needed something like CRAN so that install.packages() woul work correctly. We have an internal CRAN but I wanted to make one specific to this set of packages.…

The Evolution of Distributed Programming in R

By Paulin Shek Both R and distributed programming rank highly on my list of “good things”, so imagine my delight when two new packages, ddR (https://github.com/vertica/ddR) and multidplyr (https://github.com/hadley/multidplyr), used for distributed programming in R were released in November last year. Distributed programming is normally taken up for a variety of reasons: To speed up a process or piece of…
