Analyzing package dependencies and download logs from Rstudio, and a start towards building an R recommendation engine

In this post, I will focus on the analysis of available R packages and the behavior of its users. In essence, this involves looking at the data in two different ways (1) relationships among available R packages in CRAN and (2) tracking the behavior of R users through download logs on CRAN mirrors. I will

A Few Notes on UseR! 2014

It has been a month since the UseR! 2014 conference, and I'm probably the last one who writes about it. UseR! is my favorite conference because it is technical and not too big. I have completely lost interest in big and broad conferences like JSM (to me, it has become Joint Sightseeing Meetings). Karl has written two blog posts...

Agent Based Models and RNetLogo

by Joseph Rickert If I had to pick just one application to be the “killer app” for the digital computer I would probably choose Agent Based Modeling (ABM). Imagine creating a world populated with hundreds, or even thousands of agents, interacting with each other and with the environment according to their own simple rules. What kinds of patterns and...

Making random draws from an arbitrarily defined pdf

I recently found myself in need of a function to sample randomly from an arbitrarily defined probability density function. An excellent post by Quantitations shows how to accomplish this using some of Rs fairly sophisticated functional approximation to...

Introducing tidyr

tidyr is new package that makes it easy to “tidy” your data. Tidy data is data that’s easy to work with: it’s easy to munge (with dplyr), visualise (with ggplot2 or ggvis) and model (with R’s hundreds of modelling packages). The two most important properties of tidy data are: Each column is a variable. Each

A Handy Trick for Remote Graphics

I often create plots that require quite a bit of computation.  Ideally I would run this on what I’ll call Machine A, which is a very fast machine, but I am often far away, on Machine B.  So, I’d like to run my computation on B but display it on A. For the platforms I

There’s no mistake in the barley data

Statistics has many canonical data sets. For classification statistics, we have the Fisher's iris data. For Big Data statistics, the canonical data set used in many examples is the Airlines data. And for dotplots, we have the barley data, first popularized by Bill Cleveland in the landmark 1993 text Visualizing Data. Cleveland's innovations in data visualiation were hugely influential...
