SparkR by amplab-extras SparkR is an R package that provides a light-weight frontend to use Apache Spark from R. SparkR exposes the Spark API through the RDD class and allows users to interactively run jobs from the R shell on a cluster. NOTE: As of April 2015, SparkR has been officially merged into Apache Spark and is shipping in an upcoming release (1.4) due early summer 2015.

PSPP GNU PSPP is a program for statistical analysis of sampled data. It is a Free replacement for the proprietary program SPSS, and appears very similar to it with a few exceptions. The most important of these exceptions are, that there are no “time bombs”; your copy of PSPP will not “expire” or deliberately stop working in the future.
Example . An example of nested downloads using RCurl. This example uses RCurl to download an HTML document and then collect the name of each link within that document. The purpose of the example is to illustrate how we can combine the RCurl package to download a document and use this directly within the XML (or HTML) parser without having the entire content of the document in memory. We start the download and pass a function to the xmlEventParse() function for processing. As that XML parser needs more input, it fetches more data from the HTTP response stream.
machine learning in Python "We use scikit-learn to support leading-edge basic research [...]" "I think it's the most well-designed ML package I've seen so far." "scikit-learn's ease-of-use, performance and overall variety of algorithms implemented has proved invaluable [...]." Testing Packages with Experimental R Devel Build for Windows · rwinlib/r-base Wiki Rtools 3.3 is in the process of being updated to use a new compiler toolchain produced by Jeroen Ooms based on GCC 4.9.3 and Mingw-W64 V3. The upcoming R 3.3 release is planning on adopting this new toolchain. Package authors using compiled code should test their packages with the new toolchain to ensure compatability. This document includes instructions for downloading the requisite versions of R, Rtools, and (optionally) RStudio to perform this testing. Step 1: Install R-devel-experimental for Windows
R Installation and Administration Table of Contents This is a guide to installation and administration for R. This manual is for R, version 3.1.0 (2014-04-10). Climate Charts & Graphs As a former Excel chart user, I want to help current Excel users make the transition to more advanced charting R with as little difficulty as possible. This post introduces my LearnR Toolkit to help Excel users move up to R in a systematic, step by step fashion. Introduction As an Excel chart user, I wanted to produce panel charts like this: After using VBA to build Excel panel charts (link), I knew I had to use a more advanced charting tool to continue my global warming, citizen climate science studies. R was the logical solution; I have made the switch to R and am now able to generate the types of charts I need to continue my citizen climate science efforts.

Integration of R, RStudio and Hadoop in a VirtualBox Cloudera Demo VM on Mac OS X Motivation I was inspired by Revolution’s blog and step-by-step tutorial from Jeffrey Breen on the set up of a local virtual instance of Hadoop with R. However, this tutorial describes the implementation using VMware’s application. One downside to using VMware is that it’s not free. I know most of the people including me like to hear the words open-source and free, especially when it is a smooth ride. VirtualBox offers an open-source alternative and thenceforth, I chose this.

RStudio, Revolution Analytics and Deducer: A Tale of Three GUIs I’m in the process of moving from SPSS to R at the moment. It’s not been the easiest of rides, but then learning how to do a core part of your job never really should be. It’s been fun, though – don’t get me wrong – it’s definitely been an adventure!! Here I’m going to review my (limited) experience with some of the GUIs available for R.
