Webinar Series - Visualization and Reproducible Reports in R
Sessions: Tuesday March 31 | Thursday April 2 | Tuesday April 7 | Thursday April 9th
This webinar series focuses on the use of ggplot2 and tidyverse packages to generate reproducible reports. The tidyverse is a collection of R packages used in data science that share the same underlying design philosophy, grammar and data structures. Data visualization is information visualization and analytics to gain insight into the underlying data. Visualizations are useful for summarizing large amounts of data to examine trends and patterns and to help users understand data in a visual context (e.g. no more long tables). Data visualization has grown with the advent of interactive reports and tools made available online. Static graphs can be made interactive with pop-ups, animations, panning and zooming and many other features. Libraries in R are built for interactive web display and users are no longer required to learn multiple languages in order to display and visualize their data – All can be done in R!
RMarkdown https://rmarkdown.rstudio.com/ allows for dynamic outputs and formats of your R analysis. RMarkdown can create fully reproduceable reports and can be written in R, Python and SQL. The main benefit for using RMarkdown in research settings is the generation of a template for a report that will be output into Word, PDF or an HTML file. So, when you inevitably have to go back to change your analysis, you can do it all in RMarkdown and create a revised report in no time.
The webinar series will be divided into four 1.5-hour sessions. Background theory and live demos will be presented during each live session, with take-home practice assignments for some sessions. This course is not a statistics or analysis course but will be using tidyverse packages to summarize and shape data for the purpose of data visualization.
Prior required knowledge
Familiarity with R is an asset though not mandatory for enrollment.

The interactive webinar software will provide remote access for students to view the instructor's screen, listen to the lecture in real time, and ask questions. The instructor will provide lecture slides (PowerPoint) and required readings prior to the start of the webinar. For practice between webinar sessions and for follow up study, students will also receive training data and programming code for R.
Students can download the R software package for use on their computers through this site: https://www.rstudio.com/products/rstudio/download/
