Among the many reasons to use data.table in your code (which includes the more common answers of speed, memory efficiency, etc.) is the syntax. The syntax is concise, predictable, and R-centric. In this post, I’d like to show how these feature...

The {bscui} R package, made recently available on CRAN, has been written to transform SVG images into interactive figures. It can be used to display data on a drawing in a report or to interact with the drawing in a R {shiny} application. The...

Compress the size of your images with R, resmush and reSmush.it

We’ve released the newest version of NIMBLE on CRAN and on our website. NIMBLE is a system for building and sharing analysis methods for statistical models, especially for hierarchical models and computationally-intensive methods (such as MCMC,Laplace approximation, and SMC). This release provides new functionality as well as various ...

Correlation heat maps are pretty easy to create with {ggplot}. But there are some things you have to watch out for. For example, ggplot doesn’t use the correct colors for such a chart by default. In this blog post, I show you how to create a cor...

The R Consortium recently talked with Natalia Andriychuk, Statistical Data Scientist at Pfizer and co-founder of the RTP R User Group (Research Triangle Park in Raleigh, North Carolina), to get... The post Natalia Andriychuk on RUGs, Pfizer R Center of Excellence, and Open Source Projects: Fostering R Communities Inside and ...

Drumroll please……………….!!!!! With the addition of these 7 new books, the collection now stands at over 400 entries of (mostly) free R books! Many thanks to Markus Gesmann, Jacobus, Max Cotera, Luis, Olivier Leroy and Gary for their latest contributions. This a truly a one-of-a-kind resource. I want to give … The post ...

In the previous article we made our first steps in Object Oriented Programming in R and learned that there are multiple ways of doing it. In this article, we will dive deeper into the S3 system – the first object-oriented system in R. Fun fact: if you have used R, you ...

After 5 months of work, Philipp Baumann and myself are happy to announce that our package, {rix} is getting quite close to being in a state we consider “done” (well, at least, for a first release). We plan on submit it first to rOpenSci for review, and later to CRAN. But ...

While simulating from a mixture of standard densities is relatively straightforward, when the component densities are easily simulated, to the point that many simulation methods exploit an intermediary mixture construction to speed up the production of pseudo-random samples from more challenging distributions (see Devroye, 1986), things get surprisingly more complicated when ...

In the grand tapestry of statistical analysis, the threads of correlation and covariance weave a complex narrative, telling stories hidden within data. Like twin stars in a vast galaxy of numbers, these concepts illuminate the relationships and pattern...

Shiny apps are very often used for quick prototyping and proof of concept. However, if you want to use a Shiny app in production and make it attractive to the users, you need to make sure that the app is not only functional but also visually appealing and efficient. When ...
