Michael Liu takes us on a tour of the Floating Solar Explorer, an interactive, GIS-based R Shiny web app that visualizes water reservoirs alongside economic data and political boundaries. Along with the website itself, the presentation explores certain aspects of the data generation process using R and provide an introduction to R Shiny.

Michael gives us a brief overview of the City of Cohoes Floating Solar project and the role the Floating Solar Explorer played in winning important grants, and then demonstrates and describes the structure of the app, including some of the performance challenges imposed by the size of the datasets. If you're interested in Shiny apps in general or apps that utilize geo-based data in particular, this is the RPIrates for you!

D2ARC Final MiniConference (17 Aug 2022)
August 23, 2022

Data-Driven Alzheimer's Research Challenge (D2ARC) Final MiniConference (17 Aug 2022)

D2ARC Description: The goal of this research training experience was to expose mature students / researchers to the basics of the R programming language and related tools and techniques available for analyzing omics-scale single-cell RNA sequencing data. D2ARC focused on the application of basic data analysis techniques such as data visualization and manipulation for drawing biological insight from high-dimensional next generation sequencing datasets. A case study approach was used to provide immediate immersion in the research problem; participants focused on a high-dimensional single-cell RNAseq dataset generated by the researchers Bowles et al. with the Neural Stem Cell Institute in 2021, to study frontotemporal dementia and related tauopathies (like Alzheimer’s) in 3D brain organoid models. Students worked individually to conduct analyses of this dataset for prospective translation into real-world, publishable clinical disease research. As the final MiniConference demonstrated, students emerged with concrete, practical skills for conducting data science with R, as well as extracting knowledge and insight from single-cell RNAseq data.

Using near-real-time, anonymous WiFi data from more than 1300 wireless access points on campus, students working with the Rensselaer IDEA's Data INCITE program during the Summer and Fall 2020 terms created an app to help students easily identify crowded and open spots around campus.

RPIrates Tutorial: Simple Database Access with R
March 11, 2021

Take some time out from your busy week to talk about database access with R!

In this informal tutorial we'll share some recent experiences using remote and in-memory SQL databases (MySQL and SQLite) to access and analyze near real time, aggregated RPI WiFi data for the RPI SafeCampus and StudySafe applications. As time permits we may also cover our use of ElasticSearch, esp. in our COVID Twitter project, and SPARQL endpoints (Blazegraph, StarDog) as data sources.
