This paper argues that the R language and its packages are effective tools for spatial accessibility analysis. To support the argument, it then provides the case study that exploits the functionality of R and analyzes the spatial accessibility to medical clinics. In the case study, we first demonstrate that we can calculate the values of accessibility measures very effectively, using R's matrix function. We also demonstrate that the spatial distribution of the calculated values can be visualized only by some R coding. We further demonstrate that R and some packages enable us to determine whether the inequality of the accessibility to clinics is significant and to detect the ‘cool spots’ of the accessibility, in a reasonable manner. We conclude the paper with suggestions for future work.
