If you haven’t explored the RStudio website in a while, your next visit may include a pleasant surprise. I recently went to the Tidymodels page, just to see what was new and was immediately drawn into the new landscape imagined by the RStudio education team. Clicking on Get Started ...

We are in the middle of a mind-boggling natural experiment here in the United States. In spite of the advice from the CDC and dire warnings from our nation’s health care experts, millions of Americans will travel over the long holiday weekend. Although the number of people flying is ...

One hundred fifty-six new packages made it to CRAN in October. Here are my “Top 40” selections in eight categories: Computational Methods, Data, Epidemiology, Mathematics, Machine Learning, Statistics, Utilities, and Visualization. Computational Methods mcmcensemble v 2.0: Provides ensemble samplers for affine-invariant Monte Carlo Markov Chain algorithms which allow a faster convergence for ...

In two recent posts, one on the Disease Progression Model and the other on Fake Data, I highlighted some of R's tools for simulating data that exhibit desired correlations and other statistical properties. In this post, I’ll focus on a sma...

Two hundred thirty-six new packages made it to CRAN in September. Here are my “Top 40” picks in eleven categories: Computational Methods, Data, Finance, Genomics, Machine Learning, Mathematics, Medicine, Statistics, Time Series, Utilities and Visualization. The large number of packages and, in my opinion, the high percentage of high quality work ...

The Delphi epidemiological forecasting group at Carnegie Mellon University is undertaking a massive effort to develop leading indicators for COVID-19 outbreaks, and if you are an R or Python developer you can help. Delphi is working with both Facebook and Google to analyze the data from daily surveys that ask ...

In a previous post, I showed some examples of simulating fake data from a few packages that are useful for common simulation tasks and indicated that I would be following up with a look at simulating survival data. A tremendous amount of wo...

In this final post of the six part series on R package integration with modern reusable C++ Code using Rcpp, we will look at providing documentation for an R package. To review, we previously covered the following topics: Installation and ...

Jay Ulfelder, PhD, serves as Program Manager for the Nonviolent Action Lab, part of the Carr Center for Human Rights Policy at the Harvard Kennedy School. He has used R to work at the intersection of social science and data science for nearly two decades. Where are people in the ...

One hundred sixty-one new packages made it to CRAN in July. Here are my “Top 40” picks in seven categories: Computational Methods, Data, Genomics, Machine Learning, Science, Statistics, and Utilities. Computational Methods libgeos v3.8-1-3: Implements API access the Open Source Geometry Engine GEOS which can be used to write ...

If you are looking for a place to monitor expert forecasts for United States weekly and cumulative COVID-19 deaths, you can’t do any better than the Reich Lab (University of Massachusetts) COVID-19 Forecast Hub. The same is true for data scientists who may be seeking to publish their own ...

Daniel Hanson is a full-time lecturer in the Computational Finance & Risk Management program within the Department of Applied Mathematics at the University of Washington. In the previous post in this series, we looked at some design considerations when integrating standard and reusable C++ code into an R package. Specific emphasis ...

Two hundred ninety new packages made it to CRAN in June. Here are my “Top 40” picks in ten categories: Computational Methods, Data, Genomes, Machine Learning, Medicine, Science, Statistics, Time Series, Utilization, and Visualization. Computational Methods Rfractran v1.0 Implements the esoteric, Turing complete FRACTRAN programming language invented by John Horton Conway. ...
