Introducing {pmtiles}: an #rstats package to create, view, and interact with PMTiles.

PMTiles is one of the most exciting geospatial innovations in recent years. Map tiles are stored & served from a single file, making massive geospatial data visualization widely accessible.

Updates are underway in the {stats19} #rstats package, the quickest way to access large, high-quality collision datasets with geographical location and dozens of other variables at collision, vehicle, and casualty levels: new contributor (Blaise 🔥) + new data almost ready to launch 🚀

Yep, working well. Too bad the macOS26 design is terrible... Thankfully this has no impact on how Positron / VScode / RStudio look.

Removing transfers.txt following the advice here github.com/ipeaGIT/r5r/... helped build a routable graph. I suppose instead of transfers.txt r5 just finds the time overlaps using schedules and establishes transfers on walking proximity via OSM walking graph.

Store R5 gtfs parse errors by mattwigway · Pull Request #516 · ipeaGIT/r5r

This stores parse errors that R5 encountered when parsing GTFS, which are accessible by running gtfs_errors(r5r_network). For example, with the network we've been using to debug: > r5r_netwo...

Since the first release in December 2024, the 𝐬𝐩𝐚𝐧𝐢𝐬𝐡𝐨𝐝𝐝𝐚𝐭𝐚 ( ropenspain.github.io/spanishoddata/ ) was downloaded 2200+ times. Over the summer we conducted two workshops on the package and the data: at AGIT Conference (www.ekotov.pro/agit-2025-sp... ) and at IC2S2 (www.ekotov.pro/spanish-open... )

If you want to understand origin-destination data, visualisation is key. The {flowmapblue} package provides functions for creating interactive maps showing bidirectional flows. Just-discovered bonus: you can add time filters to see the 'pulse' of a city: ropenspain.github.io/spanishoddat...

It's day 2 of the Data Science for Transport Planning course here at Leeds. We'll be covering spatio-temporal data analysis, multi-modal routing, route network analysis, and how to go from data science results to a web application. Watch this space for #OpenAccess materials!

I also noticed that now a simple purrr::map is MUCH faster with mirai than fancy furrr/future_maps/applies/etc with future. Unless the future plan is also future.mirai (future.mirai.futureverse.org) of course ;)

r5r was one of the key reasons I started working on rJavaEnv 👌, as I was annoyed by Java setup. Only later I dug deeper and found out there were 100s of Java dependent packages

Speaking of tabulapdf, could everyone please have a look at the personal message from the dev pacha.dev/blog/2025/08... he needs some help

@kylewalker.bsky.social Thanks for sharing! Do you remember, which R packages you use(-d) in your work that require rJava and/or Java?

This version is not yet on CRAN, I will let the dev version ( github.com/e-kotov/rJav... ) cool down a bit and allow time for testing, hopefully but some of you!

🚀 #rJavaEnv #rstats (helper for 100+ Java-dependent packages ) is about to get its biggest update yet. Just in time for ~10k downloads, Java 25 release, and its CRAN bday!

👉 Dev version: github.com/e-kotov/rJav...

New: (1) full Linux support + (2) env setup so you can build {rJava} from source.

The Geocomputation with Python #opensource book project just got an upgrade, with Python 3.12 now the default in the devcontainer.

You can launch a full dev environment directly from your browser with GitHub Codespaces. Give it a try here: github.com/codespaces/n...

Result: issue with Finland-wide GTFS: "Error calculating route: Assertion on 'r5r_network' failed: None of the GTFS feeds used to create the transit network can contain a 'frequencies' table. Try using gtfstools::frequencies_to_stop_times() to create a suitable feed." So I will try gtfstools

Egor Kotov 🌐🏃‍♂️🚊🚋🚙 @ekotov.pro · Sep 5

OK, so something hacky I did, is I created the network files with @r5py.bsky.social ignoring GTFS errors (in a file already fixed by gtfsclean), moved those network files into #r5r to make it think it made them, added json that #r5r needs, loaded it up into github.com/e-kotov/r5rgui to explore

Consider joining us in beautiful Bologna for the largest gathering of population scientists in Europe…

It is also a wonderful opportunity for those of us who are based outside of Europe to catch up with the latest demographic developments in the old continent.

Hope to see you there!

Zero #rstats dependencies for end users! Early days but promising 👀

@htenkanen.bsky.social @waeiski.bsky.social , hi, have you had any experience with these Finland-wide GTFS files and #r5r or #r5py? www.fintraffic.fi/fi/digitaali... I am having issues with making those work, routing just fails. I suspect there must be some cleaning done on those GTFS files.
