New #rstats package: rtileserver. We've always been constrained by how time-consuming it is to map large-scale data (more than ~20k points) With this, we do it with one line (and a database). https://t.co/RCqypeoygJ Thanks to @kyle_e_walker and @giswqs for demos.

The 1.4 release of @duckdb supports using a DuckDB database to serve vector tiles! Of course, I had to try this out in R. Check it out: all 242,000 US Census block groups dynamically served as vector tiles from a DuckDB database, displayed on a MapLibre map from R in Positron.

Descobri um pacote interessante para mapas. Aliás, rodou bem mais leve que o tradicional de mapas. Peguei os microdados do Enem de 2024 e plotei esse mapa com médias de redação para cada municipio, apenas escolas públicas.

🔍 ¿Tu análisis de clustering es fiable? Aprende a validarlo 🧠 El clustering no termina cuando el algoritmo te devuelve unos grupos. ¡Eso es solo el principio! 😉 Antes de sacar conclusiones, asegúrate de que tu agrupación es buena, estable y coherente.👇🧵

The new `enable_shiny_hover()` function in mapgl for #rstats lets you use your mouse's position as a Shiny input! Be judicious with how you use it for performance reasons... but it unlocks so many possibilities. Example: Census tracts that restyle based on your cursor position

mapgl v0.3 for #rstats gives you the ability to customize your map legend's appearance with no CSS required. Use the `legend_style()` function to style the legend container, typography, and elements - and even add a drop shadow if you'd like. More info: https://t.co/NDdU1MjxF8

Editable features are in the development pipeline for the #rstats {mapgl} package! I've got a ways to go before it is ready to share, but it's going to open up a whole realm of possibilities for interactions with your spatial data in your R sessions / Shiny apps.
