Gentle introduction to R

The R language is closely tied to statistics. It’s ancestor was named S, because it was a language for Statistics. The open source descendant could have been named ‘T’, but its creators chose to call it’R.’ Most people learn R as they learn statistics: Here’s a statistical concept, and here’s how you can compute it in R.

Speeding up the Cluster Bootstrap in R

Back in January 2013 I wrote a blog post showing how to implement a basic cluster/block bootstrap in R. One drawback of the cluster bootstap is the length of time it takes to sample with replacement and create the data samples. Thankfully some of the comments on my previous post illustrated simple ways to get […]

Data frames and tables in Scala

Introduction To statisticians and data scientists used to working in R, the concept of a data frame is one of the most natural and basic starting points for statistical computing and data analysis. It always surprises me that data frames aren’t a core concept in most programming languages’ standard libraries, since they are essentially a … Continue reading Data frames and tables in Scala

Calling R from Scala sbt projects using rscala

In this post I will show how to call R from Scala code. I have previously described how to do this using jvmr. This post is really just … Continue reading Calling R from Scala sbt projects using rscala

Calling Scala code from R using rscala

Introduction In a previous post I looked at how to call Scala code from R using a CRAN package called jvmr. This package now seems to have been replaced by a new package called rscala. Like the old package, it requires a pre-existing Java installation. Unlike the old package, however, it no longer depends on … Continue reading Calling Scala code from R using rscala
