My paper, Visualization techniques for journey to crime flow data, has been recently published in a special issue in CaGIS on crime mapping. Always feel free to email me for off-prints of published papers, but the pre-print of this one I posted on SSRN as well.
There is an annoying error that crept into the paper, in that the footnote linking to the results to replicate the maps and graphs says "REDACTED FOR ANONYMITY" – which is my fault for not pointing it out to the copy-editor. The files are available here. They are certainly not easy to walk through, so if you want help replicating any of the maps for your own data and can’t figure out my code feel free to send me an email. I would like to make an R package to make maps like below eventually, but that is just not going to happen in the forseeable future.
