In this introductory post, I preview a series of four blog posts to accompany a book my co-authors and I wrote, Data Science in Education Using R. In the coming weeks, we’ll be sharing about the people and tools in the R community that inspired us to write DSIEUR.
Machine learning models come in many shapes and sizes. While deep learning models currently have the lion’s share of coverage, there are many other classes of models that are effective across many different problem domains. This post gives a short summary of several rule-based models that are closely related to tree-based models (but are less widely known).
If you been been trying to make sense of the various published COVID-19 models but are not an epidemiologist, you may want to acquire some background knowledge. One good way to do this is to find a handful of relevant R packages with documentation and pointers to source material. This post provides a guided search and turns up some R packages that may be of interest to novices and experts alike.

Two hundred ninety-six new packages made it to CRAN in March. Here are my “Top 40” picks in ten categories: Computational Methods, Data, Machine Learning, Mathematics, Medicine, Science, Statistics, Time Series, Utilities, and Visualization.
Computational Methods celltrackR v0.3.1: Provides a methodology to analyze cells that move in a two- or three-dimensional space. While the methodology has been developed for cell trajectory analysis, it is applicable to anything that moves including animals, people, or vehicles.

Git and its online extensions like GitHub, Bitbucket, and GitLab are essential tools for data science. While the emphasis is often on collaboration, Git can also be very useful to the solo practitioner.
The RStudio IDE offers Git functionality via a convenient web-based interface (see the “Git” tab), as well as interaction with git via the command-line (via the “Console” tab, or via the “Git” tab’s “More”->“Shell” menu option).
If you are a data scientist with a built-out set of modeling tools that you know well, and which are almost always adequate for getting your work done, it is probably difficult for you to imagine what would induce you to give them up. Changing out what works is a task that rarely generates much enthusiasm. Nevertheless, in this post, I would like to point out a few features of tidymodels that could help even experienced data scientists make the case to give tidymodels a try.
In today’s Reproducible Finance post, we will explore state-level unemployment claims which get released every Thursday. The last few weeks have shown huge spikes in those claims, of course, due to the coronavirus and statewide lockdown orders, and it got me wondering how these times will look to data scientists in the future.
Let’s start by importing unemployment insurance claims data for Georgia. This is a data series that’s reported by all 50 states.
