Rutgers University Libraries Data Services Workshop Series (New Brunswick)

Spring 2020

In response to the COVID-19 situation, all workshops will be moved online for the period after Spring Break.

Current information about online (Webex-based) workshops is posted here, with Webex links to workshops made available as they are created.  The situation is changing daily, so please register for workshops of interest to receive updated information and reminders.

Introduction to SAS

This workshop provides an introduction to SAS, covering the basics of navigation, loading data, graphics, and elementary descriptive statistics and regression using a sample dataset. 

SAS is a powerful and long-standing system that handles large data sets well, and is popular in the pharmaceutical industry and health sciences, among other applications.

R for data analysis: a tidyverse approach 

  • Thursday, March 26 – 2:00-3:30 pm, Webex conference  (Instructor, Ryan Womack)

The session introduces the R statistical software environment and basic methods of data analysis, and also introduces the "tidyverse".  While R is much more than the "tidyverse", the development of the "tidyverse" set of packages, led by RStudio, has provided a powerful and connected toolkit to get started with using R.  Note that graphics and data manipulation are covered in subsequent sessions.

R graphics with ggplot2 

  • Thursday, April 2 – 12:00-1:30 pm, Webex conference  (Instructor, Ryan Womack)

The ggplot2 package from the tidyverse provides extensive and flexible graphical capabilities within a consistent framework.  This session introduces the main features of ggplot2. Some prior familiarity with R is assumed (packages, structure, syntax), but the presentation can be followed without this background.  

R data wrangling with dplyr, tidyr, readr and more 

  • Thursday, April 2 – 2:00-3:30 pm, Webex conference (Instructor, Ryan Womack)

Some of the most powerful features of the tidyverse relate to its abilities to import, filter, and otherwise manipulate data.  This session reviews major packages within the tidyverse that relate to the essential data handling steps require before (and during) data analysis.

R for interactivity: an introduction to Shiny 

  • Thursday, April 16 – 12:00-1:30 pm, Webex conference (Instructor, Ryan Womack)

Shiny is an R package that enables the creation of interactive websites for data visualization.   This session provides a brief overview of the Shiny framework, and how to edit and publish Shiny sites in RStudio (with shinyapps.io).  Familiarity with R/RStudio is assumed.

R for reproducible scientific documents: knitr, rmarkdown, and beyond 

  • Thursday, April 16 – 2:00-3:30 pm, Webex conference  (Instructor, Ryan Womack)

The RStudio environment enables the easy creation of documents in various formats (HTML, DOC, PDF) using Rmarkdown, while knitr allows the incorporation of executable R code to produce the tables and figures in those documents. This session introduces these concepts and other packages and practices supporting reproducibility with the R environment.

Also see the Digital Humanities workshops series for several workshops involving R.

About R

R is open source software for statistical analysis.  Being open source (Gnu GPL licensed) doesn't just mean that the software is free.  It means that you can use it for a variety of applications, and install it virtually anywhere you'd like, without any restrictions.  Open source also means that the code for all statistical procedures and analysis can be independently checked and verified.  The activity community of R users is constantly developing new add-on packages that use the latest techniques, which you are free to do as well.  And, being free, you can always have access to the latest version of the software, no matter where you are.

R is also a programming language, which makes it easy to document, reuse and reproduce all the steps of your statistical analysis. 

You can get R, and full documentation on R, at www.r-project.org or by downloading from any CRAN mirror (Comprehensive R Archive Network).
