R_Workspace_HKI_healthy_food_3D_accessibility

This directory provides the source code, raw data and raw results from the paper titling "3D Walking Accessibility in Practice: Exploring the Imperfections from Data, Method, and Assumptions of Human-Space Interaction" from the <i>International Journal of Geographical Information Science</i>.This workspace includes the R scripts for preprocessing the data, conducting the analysis, and producing the results.The "data" folder includes all of the raw data. The "Readme.txt" in each folder inside provides the data sources. The "Preprocessed_data" folder within the "data" folder contains all preprocessed data generated by the R script "DataPreprocess.qmd". The "DataPreprocess.qmd" records the workflow of preprocessing the data for analysis.The "rFunction.qmd" file recorded all customised R functions for this study. The "Analysis01_cal_access.qmd" and "Analysis02_formalAnalysis.qmd" files record the R code for conducting the analysis and producing the results. Please first run the code in "rFunction.qmd" to reproduce the data preprocessing and data analysis. The "workspace.Rproj" is the R workspace for conducting the computation. You can open this workspace and import the R scripts from "rFunction.qmd", "DataPreprocess.qmd", "Analysis01_cal_access.qmd", and "Analysis02_formalAnalysis_update.qmd".The "result" folder comprises all raw figures, tables, and GIS data. Because R cannot produce the 3D map. Therefore, the "Qgis" folder comprises the QGIS files for visualising and mapping the produced GIS data. We used the Qgis2threejs plugin to visualise the 3D scene.

本目录提供了《国际地理信息科学期刊》（International Journal of Geographical Information Science）刊载的题为《实践中的三维步行可达性：探索数据、方法及人-空间交互假设的不完善之处》一文的源代码、原始数据与原始结果。此工作空间包含用于数据预处理、分析执行及结果生成的R脚本。"data"文件夹涵盖所有原始数据，其内各子文件夹中的"Readme.txt"文件说明了数据源。"data"文件夹下的"Preprocessed_data"子文件夹包含由R脚本"DataPreprocess.qmd"生成的所有预处理数据，而"DataPreprocess.qmd"记录了用于分析的数据预处理流程。"rFunction.qmd"文件记录了本研究的所有自定义R函数；"Analysis01_cal_access.qmd"与"Analysis02_formalAnalysis.qmd"文件记录了执行分析及生成结果的R代码。请先运行"rFunction.qmd"中的代码，以复现数据预处理与数据分析过程。"workspace.Rproj"是用于计算的R工作空间，您可打开此工作空间并导入来自"rFunction.qmd""DataPreprocess.qmd""Analysis01_cal_access.qmd"及"Analysis02_formalAnalysis_update.qmd"的R脚本。"result"文件夹包含所有原始图件、表格及地理信息系统（GIS）数据。由于R无法生成三维地图，"Qgis"文件夹包含用于可视化和制图所生成GIS数据的QGIS文件；我们使用Qgis2threejs插件实现三维场景的可视化。
