PSet 2: Portal rodent experiment
EE BIOL C177/C234, Fall 2026

1. Extract the ZIP. Open PSet2_Portal.Rproj inside the extracted folder.
2. Rename PSet2_LastName.qmd with your last name and edit its author.
3. Read the assignment at https://clsong.github.io/EEB_C234/PSet2.html
4. Read data/data_dictionary.txt before analyzing the files.
5. Install packages in the Console as described in the assignment. Render
   the starter once before adding your work; its empty sections are intentional.
6. Keep your code in the report and interpret results between code chunks.
7. At the end, record packages with renv and check a fresh render. Submit the
   files listed in the assignment, excluding installed libraries and caches.

The four CSV files are a frozen teaching extract, not a complete copy of the
Portal database. Blank CSV cells indicate missing values. The species code
"NA" means Neotoma albigula; read_csv(..., na = "") preserves it.
