COVID-19

Ongoing Start: Summer 2021

Manipulated 6 different data sets from the New York Times github repository with tidyverse packages in R to create data visualizations on Covid-19 in America and counties in Oregon. Presented via github repositories, and updated regularly.

Rsite

Complete Start: Spring 2021 End: Summer 2021

Created using github repositories, rsite includes 4 different class projects from Statistics-363 : Introduction to R. Each project includes various techniques of data manipulation, statistics, analysis, and visuals in the form of various tables, graphs, and a map.

Inspired by Rsite, this site was created using R Studio, github repositories, and a little CSS. Included are instructions on how the project was created, data and visuals on classical ballet, and one of my statistics homeworks done compeltely in R.

Incomplete Start: Summer 2021 End: Fall 2021

Second blog and first personal website created using blogdown, github, and netlify. 8 blog posts from the Fall of 2021 including how to use APIs, examples from regression annalysis, proofs, and a few other micro posts from undergrad. This blog was scrapped for one with more features already included such as day / night mode, and contact form.
