<p>On Nov 28 2017, Brian Connolly came and visited and taught us how to do basic data analysis in R.</p> <p>He in particular showed us how to do a Linear Discriminant Analysis (LDA) and Principal Component Analysis (PCA).</p> <p>Attached are three of the data files Carl Pfendner prepared for us to analyze (ARA data, including simulation, force triggers, and RF triggers).</p> <p>Also attached is some R code that shows how to set up the LDA and the PCA and how to plot their result. You are meant to run each line of the code in r by hand (this is not a functioning R script I don't think).</p> <p>Go here (https://www.r-project.org/) to learn how to download R. You will also probably have to download GGFortify. To do that, open an r session, and type "<em>install</em>.packages('<em>ggfortify</em>')".</p> Encoding: HTML ELCode plain Suppress Email notification
