We feel very honored to host meetup and class offered by Kaggle #1 ranked Data Scientist, Owen Zhang and book author of Applied predictive modeling, Max Kuhn. Featured R experts meetup Featured talk given by Kaggle world ranked #1 Owen Zhang

I’ve put together an updated version of my partools package, including Snowdoop, an alternative to MapReduce algorithms. You can download it here, version 1.0.1. To review: The idea of Snowdoop is to create your own file chunking, rather than having something like Hadoop do it for you, and then using ordinary R coding to perform … Continue reading...

Introduction The purpose of this post is to show how to use Boost::Geometry library which was introduced recently in Rcpp. Especially, we focus on R-tree data structure for searching objects in space because only one spatial index is implemented - R-tree Currently in this library. Boost.Geometry which is part of the Boost C++ Libraries gives us algorithms for solving geometry problems. In this library, the...

Today we’re excited to announce htmlwidgets, a new framework that brings the best of JavaScript data visualization libraries to R. There are already several packages that take advantage of the framework (leaflet, dygraphs, networkD3, DataTables, and rthreejs) with hopefully many more to come. An htmlwidget works just like an R plot except it produces an interactive web

by Matt Sundquist co-founder of Plotly R, Plotly, and ggplot2 let you make, share, and collaborate on beautiful, interactive plots online. Let's see what we can do with the topographic data from Auckland's Maunga Whau Volcano that comes with R. Copy and paste this R code to make your first plot. The basic idea is: use ggplot2 code, add...

This tutorial describes how to integrate computable R code (and outputs) in a LaTeX documents in a such a way that a single file can generate two (or more) PDF files. This trick is particularly useful for creating worksheets for R courses. A very small introduction to integrating R code in LaTeX files R code

I have some experience teaching R programming (see, for instance, my online course). One of the atypical choices I make is to start by teaching Hadley Wickham’s ggplot2 package, rather than the built-in R plotting (see these videos). Many times that I mention this choice to others involved in statistics education, they treat it like a mistake...

As a user Imagine that you are starting to learn how to use a specific R package, lets call it foo. You will look at the vignette (if there is one), use help(package = foo), or look at the reference manual (for example, devtools' ref man). Eventually, you will open the help page for the function(s) you are interested...

In the first post of this new blog I’ll outline how I’ve set the blog up. writing posts in Rmarkdown converting posts to markdown from R push to Github where Jekyll renders the markdown organising all as an RStudio project What I wanted I wanted to be able to write about R related things without having to...
