#rstats #spanishoddata will be presented next week at the MNO-MINDS ESSnet Project Final Conference cros.ec.europa.eu/event/mno-mi... at OECD office in Paris. Access Spanish Open Human Mobility Big Data in a reproducible way that is analysis ready. ropenspain.github.io/spanishoddata/

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!

Don't miss this chance!!! 🇫🇷 netmob.org/www25/ v4.event-vert.org/en/netmob2025/

From a Q2 (according to @elsevierconnect.bsky.social ) journal asking for a review. They are not even trying. According to them, I have an "expertise in areas related to linguistics (if any)" [I love this "if any"!] , makes me "an ideal candidate to review the manuscript".

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

🚀 #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...

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!

Prototyping #rshiny apps to native #electron desktop apps: shinyelectron::export() → #rshinylive conversion → .dmg → Native Mac app 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.

#Accessibility modelers using #r5r #rstats, check this GUI for playing around with R5 network. If many people find it useful, I would get signal if I should invest any more free time into it. github.com/e-kotov/r5rgui (uses #mapgl by @kylewalker.bsky.social and #r5r by @urbandemog.bsky.social et al)

📩 If you are an author of a paper using DuckDB, please submit your work following the guidelines at the bottom of the page.

We just launched the “DuckDB in Science” site, a curated collection of papers, lectures and podcasts about DuckDB in research: duckdb.org/science/ 🎡 If you would like to learn more about DuckDB in Science, consider joining our meetup in London this Thursday: www.meetup.com/duckdb/event...

We are going to… London! 🇬🇧✨ Save the date: 22–26 June 2026 🗓️ Stay tuned on our socials and on the website www.complexity72h.com for the calls for tutors and participants — coming soon! 🚀

New #rstats github.com/e-kotov/grid... Creates GISCO/INSPIRE-compliant grids with IDs like ‘CRS3035RES1000mN3497000E4448000’ or ‘1kmN3497E4447’. The resulting grids are always aligned to rounded coordinates as per INSPIRE spec. No more downloading 1.5-2.6 GB files from Eurostat. #CRAN -ready..?

TIL about SciServer.org: Free scientific computing platform with persistent accounts (#NSF-funded). All the power of #JupyterHub without the setup hassle. Focus on building great teaching + research notebooks, not infrastructure! #OpenScience

{multideploy} is now on CRAN! 🎉 This #rstats 📦 streamlines file deployments across multiple #GitHub repositories. Update CI workflows, configs, and templates at scale with precision + automated PRs. Install with: install.packages("multideploy") CRAN: cran.r-project.org/package=mult...

Many of you already heard about this new algo that's faster than Dijkstra ( arxiv.org/abs/2504.17033 ), here I collected 3 software implementations: 1. #python github.com/sidharthpuna... 2. #rust github.com/alphastrata/... 3. #rust + some explanations of the paper medium.com/%40adnanmaso...

New #rstats package for clustering and aggregating origin-destination data just dropped. For more on {flowcluster} and to get involved in the conversation, see Hussein's LinkedIn post here: www.linkedin.com/posts/hussei...

So what started as a "thought leadership" post idea has now turned into a TurfJS R wrapper for you all to use: walker-data.com/mapgl/articl...

Get 9-30x speed doing areal-weighted interpolation with my new {𝐝𝐮𝐜𝐤𝐬𝐟} #rstats package compared to {sf}/{areal}. Experimental, but tested against both {areal} and {sf}. www.ekotov.pro/ducksf/ Despite the costs of <> data between formats, the performance is impressive, thanks to @duckdb.org #spatial

Funny how you can make a totally empty GitHub repo with a catchy name and still get stars in the first week. I guess people just see it in their feed and click. Mine only has a .gitignore file 😏 Now comes the hard part = living up to the name 🙈

We just published a deep dive on spatial joins in DuckDB by @maxxen.bsky.social. In this blog post, Max explains how spatial joins evolved in DuckDB and how the current operator harnesses R-Trees. Read the full post at duckdb.org/2025/08/08/s...

Client-side GIS analysis in #rstats via TurfJS is now possible in the {mapgl} package! Calculate buffers, intersections, spatial filters, Voronoi polygons, and more *in the map* This is HUGE for performant spatial analysis in Shiny apps. Vignette: walker-data.com/mapg...#rstats

that was an awesome talk and dive into R spatial. I learned about the "secret" `DBI::dbExecute(con, "CALL register_geoarrow_extensions();")` (combine that with `library(geoarrow)`) which makes it so much easier to move sf between #Rstats and #DuckDB

Gemini 2.5 Pro isn’t any good for Typst either. It thinks long and hard, but the result is a flop.

It's been studied a bit, but not enough IMO (occasionally I contemplate it...) Lucchesi & Wikle (doi.org/10.1002/sta4...) discuss it (and link to earlier work I've only found illegible scans of: doi.org/10.1016/S009..., and Preston & Ma did a study on some variations (doi.org/10.1109/TVCG...)

The cool things you sometimes find in the CRAN submission queue. harriet-mason.github.io/ggdibbler/ a new package to visualize uncertainty. #rstats

Sonnet 4 is infinitely better than any of the GPT 4/o4 models for Typst, in my subjective opinion and recent experience. I don't know if it is trained on more recent Typst docs, or if it is just better at getting the logic of previously unseen code, but it solved my problem, gpt whatever did not not

Here's an ad that Google Opal created for #rstats #spanishoddata ropenspain.github.io/spanishoddata/ The flows map in the end is not so good, but the overall idea of the package is represented quite well. Quickly get OD flows from Spanish big open human mobility data.

While R is far from “dead” I do think we in the #rstats community need to consider this chart from @jscarto. R has seen remarkable growth over the past decade, but has declined since 2022. Why is this the case? Three notable things happened in 2022:
