ECI 587 Anna Engelke Final Project
Step 0: PREPARE THE ENVIRONMENT The functions for k-means clustering are included in base level R, but let’s install some packages for tidying and visualizing the data more easily. install.packages("pacman") #makes loading other packages much easier ## Installing package into '/cloud/lib/x86_64-pc-linux-gnu-library/4.3' ## (as 'lib' is unspecifie...

ECI 587 Preparing Data for Final Project
Part 1: Data Preprocessing Time to start loading packages! Since this assignment mostly focuses on preparing data, I’ll use primarily the tools we’ve used in almost every assignment, while also installing the pacman package to streamline things. As I continue through this assignment, I’ll return to this section and add packages as needed (e.g...

ECI 587 Naive Bayes
Prepare the Environment Package loading time! I’ll use some of the ones from the walkthrough, along with the pacman package and the caret package. install.packages("pacman") ## Installing package into '/cloud/lib/x86_64-pc-linux-gnu-library/4.3' ## (as 'lib' is unspecified) library("pacman") pacman::p_load( tidyverse, readr, magrittr, d...

ECI 587 KNN
Prepare the Environment Time to start loading packages! In this case, I’ll use the same ones that we used in the walkthrough from last week, along with the pacman package to streamline install. I left the comments from the walkthrough on the packages that are new to me, in case I need to reference them later. install.packages("pacman") ## Install...

ECI 587 Simple Regression
Prepare the Environment The pacman() package last week was new to me, and I found it very helpful! I’ve always found it annoying to install and load everything separately, nice to know there’s an alternative. I’ll also use the same packages we used in the Week 4 code walkthrough, since we’re doing similar work with linear regression. instal...

ECI 589 - Engelke Final Project
1. PREPARE 1a. Research Questions I wanted to build on the work from my Unit 3 Independent Study, where I began to explore using data exported from our staff scheduling software (Deputy) to visualize interactions among BeAM staff. I decided to be a little more ambitious this time, and target a specific cohort: the student staff who participated in...

PREPARE Research Question I work full-time as the Education Program Manager at the BeAM Network of Makerspaces at UNC-Chapel Hill. I’m just starting my research journey, but I’ve been in the field of maker education for more than a decade. One of the gaps that I see in my field is our ability to assess certain emotions, thoughts, or phenomena ...
