Shiny Apps

MCTestAnalysis

MCTestAnalysis provides a Shiny web app interface and an automatic report-generation tool featuring concepts from Classical Test Theory (CTT), Item Response Theory (IRT) and structural analysis.

Course instructors can use this app to upload the results of multiple choice tests and analyze and explore the performance of their tests. Through the app they can assess the difficulty of each question, determine how well the test measures performance and identify problematic or confusing question options. And more!

ermoji

ermoji is a fun, silly, whimsical and entirely indispensable RStudio addin for searching, finding, and copying emojis inside RStudio.

Why? Because 🤓. But also because I wanted an easy way to find the Unicode strings for emoji.

Explore Tweets from Conferences

Shiny apps for following tweets around IRL conferences

rstudio::conf(2018)

RStudio's Annual rstudio::conf() happened, but I wasn't there. So I made a tweet explorer in Shiny to follow along at home.

You can still use the app to explore #rstudioconf-related tweets, or you can go watch the talks online.

rstatsnyc 2018

When the New York R Conference kicked off, I realized I could easily repurpose the rstudio::conf() tweet explorer. The conference is over, but you can still browse the twitter record with the app.
