<p><strong>Recruitment and Engagement Reports in R for NIH funded Mobile Health Study</strong></p>
<p>Julia Henkins, MPH</p>
<p>Research Specialist at UIC Academic Internal Medicine and Geriatrics</p>
<p>Julia will be talking about how she used REDCap and the tidyverse package to capture recruitment and engagement data for a randomized controlled trial.

<p>Chris Diaz: <strong>Writing and Publishing with RMarkdown</strong></p>
<p>RMarkdown is an open source R package that adds R programming features to Markdown, a simple plain-text formatting language. RMarkdown is the basis for tools like Bookdown and Blogdown, static site generators that convert RMarkdown into HTML, PDF, and EPUB for educational, technical, or scholarly websites and blogs. We’ll cover the basics of using these packages, install them in an RStudio environment, and discuss free deployment options publishing documents to the web.</p>

<p><em>Regression and Classification with Trees in R</em></p>
<p>Regression/decision trees are regression/classification models with many advantages. In this presentation, I will introduce rpart, the most popular R package for fitting regression and decision trees. Part of this presentation will explain why regression/decision trees could be the first model to consider for many regression/classification tasks. This is also helpful for knowing what and how we can configure when constructing regression or decision trees using rpart. In addition, rpart tree outputs will be discussed with some examples.</p>
<h2 id="summer">Summer</h2>
