Thermal discomfort in urban underground metro systems

The .zip file includes: 1. An R Project (.Rproj) file, which standardizes the working environment across different computers. When users open the project, R automatically sets the project folder as the working directory, eliminating path-related issues that typically arise when code is executed on different machines or file structures. 2. A clean and organized folder structure, with all scripts and datasets placed in relative subdirectories. Because the R code uses only relative paths within the project (e.g., "data/..." instead of absolute file paths), the analysis can be reproduced identically regardless of where the user saves the project on their computer. 3. Revised and annotated R scripts, which guide the user through the analysis steps in a clear order and facilitate verification of all results.
