New series: R and big data (concentrating on Spark and sparklyr)

Win-Vector LLC has recently been teaching how to use R with big data through Spark and sparklyr. We have also been helping clients become productive on R/Spark infrastructure through direct consulting and bespoke training. I thought this would be a good time to talk about the power of working with big-data using R, share some hints, and even admit to some of the warts found in this combination of systems.

The ability to perform sophisticated analyses and modeling on “big data” with R is rapidly improving, and this is the time for businesses to invest in the technology. Win-Vector can be your key partner in methodology development and training (through our consulting and training practices).


We Can Do It

J. Howard Miller, 1943.

The field is exciting, rapidly evolving, and even a touch dangerous. We invite you to start using Spark through R and are starting a new series of articles tagged “R and big data” to help you produce production quality solutions quickly.

Please read on for a brief description of our new articles series: “R and big data.” Continue reading New series: R and big data (concentrating on Spark and sparklyr)

Practical Data Science with R errata update: Java SQLScrewdriver replaced by R procedures and article

We have updated the errata for Practical Data Science with R to reflect that it is no longer worth the effort to use the Java version of SQLScrewdriver as described.

Screwdriver

We are very sorry for any confusion, trouble, or wasted effort bringing in Java software (something we are very familiar with, but forget not everybody uses) has caused readers. Also, database adapters for R have greatly improved, so we feel more confident depending on them alone. Practical Data Science with R remains an excellent book and a good resource to learn from that we are very proud of and fully support (hence errata).

Announcing the wrapr packge for R

Recently Dirk Eddelbuettel pointed out that our R function debugging wrappers would be more convenient if they were available in a low-dependency micro package dedicated to little else. Dirk is a very smart person, and like most R users we are deeply in his debt; so we (Nina Zumel and myself) listened and immediately moved the wrappers into a new micro-package: wrapr.
