Developed two end-to-end Tidyverse data manipulation templates for the Colorado-State-University-CMB/CM515-course-2025 repository, focusing on accelerating hands-on learning and standardizing course exercises. The work involved creating R Markdown files that guide users through data loading, inspection, subsetting, and data type conversions, as well as advanced dplyr operations such as filtering, selecting, mutating, grouping, summarizing, and counting. Incorporated tidyr pivoting to demonstrate practical data wrangling techniques. Leveraged R, Tidyverse, and git-based collaboration to deliver completed templates in a single commit, improving onboarding and instructional efficiency for the course while demonstrating depth in data analysis and reproducible workflow design.
