Become a Software and Data Carpentry Instructor

Become a Software and Data Carpentry Instructor

We will be hosting an instructor training workshop for becoming certified as a Carpentries instructor on March 5-6, 2018 and we invite you to apply by Wednesday Feburary 14. The purpose of the Carpentries organization, which is a merger between the pre-existing Software Carpentry ( and Data Carpentry (, is to run workshops that provide better computational skills to scientists, including in various programming languages. The upcoming 2-day training workshop will train instructors to use educational pedagogy and best instructional practices while teaching technical subjects like programming and reproducible science.

Wildlife tracking data in R

Simona’s presentation can be found here: The RData file and RMarkdown file (used to make the rest of this post) can be downloaded at the GitHub repository here If you’re unfamiliar GitHub, you can download a zipped file by pressing the green “Clone or download” button on the right of that page. From there just unzip the folder and click on the .Rproj file (requires RStudio to be installed).

Introduction to Species Distribution Models

Check out Dr. Zhao’s presentation: This presentation was made using RMarkdown. The Markdown code is included below, however outputs from R (i.e. graphs) will only be displayed in the presentation. Download the RMarkdown file and an R script for generating data to test these scripts at the GitHub repository: Note the RMarkdown script relies on some private data, so it will not run on it’s own, but can be run using the simulated data.


In this article, we will be talking about the importance of cross-validation to choose the best model. To do this, we will show: the problem of using simple in-sample metrics for model selection with a univariate example the problem of using simple in-sample metrics for model selection with a multivariable example how to perform cross-validation using simple linear regression and some problems associated with this 1) The problem of using simple in-sample metrics for model seelction with a univariate example When dealing with a regression model, we are often interested in determining which covariates to keep in the model and which to through away.

RMarkdown and bookdown

Introduction This is an introductory post into using Bookdown. Bookdown is a powerful package that allows you to create documents embedding images, tables, and code. One great reason to use Bookdown is that you can put results and images from your code directly into your text, which reduces the chances of copying errors. For this post, I’m going to focus on creating an HTML document, though you can also create outputs in Word and PDF formats.
