Provides various utility functions for improving server-side rendered HTML applications, such as enhanced HTML templating, response caching, and HTML tag serialisation.

Creates interactive maps using MapLibre GL and deck.gl via htmlwidgets. Provides GPU-accelerated layers for points, lines and polygons, plus linked user interface components such as filters, views and summary cards for exploratory analysis and production dashboards.

Fast and memory-efficient functions to analyze and manipulate large spatial datasets. It leverages the fast analytical capabilities of ‘DuckDB’ and its spatial extension (see ) while maintaining compatibility with R’s spatial data ecosystem to work with spatial vector data.

Choosing the right standard for geospatial tiles affects speed, compatibility, and how easily your web GIS scales

Provides reusable primitives to build and serialize static SpatioTemporal Asset Catalog (STAC) documents, including catalogs, collections, items, assets, and links. The package implements the STAC specification version 1.0.0 () and is intended as a foundation for other tools, such as STAC generators and experiment catalog builders. Optional spatial metadata extraction and thumbnail rendering are supported through terra, and QGIS style parsing through xml2, when these packages are available.

This package is an implementation of the geoviz javascript library. can be used to create a wide range of interactive, zoomable vector maps, taking advantage of d3’s many features: proportional symbols, pictograms, typologies, choropleth maps, spikes, tiles, Dorling cartograms, etc. It can also be used to create pretty static vectorial maps in SVG format, suitable for editorial cartography.

Shiny-style authoring, stateless API deployment. Build the UI in R with bslib, compile it to a static asset, and serve it plus JSON routes with plumber2.

This tutorial walks through a simple point-and-click workflow starting from a GitHub repository with an app.R and Dockerfile and then shows how to connect it to Cloud Run.

Discover the essential layers of testing for robust R packages: unit tests, acceptance tests, code coverage, and mutation testing.

In this workshop in partnership with RLadies BA, participants learned how to build reproducible research workflows with R and Quarto, integrating code, results, figures, and narrative into a single document for publishing manuscripts, reports, presentations, and more.

DuckLake delivers advanced data lake features without traditional lakehouse complexity by using Parquet files and your SQL database. It's an open, standalone format from the DuckDB team.

We released Quack on May 12, 2026. Read the announcement blog post! The Quack extension turns a DuckDB instance into a server that other DuckDB instances (clients) can connect to over HTTP. This page covers the protocol at a glance and walks through basic usage on both sides of the wire. For the full list of functions, settings, and logging knobs, see the Reference. For configuring TLS and authentication / authorization, see Security. For user guides, see Guides. Warning Quack is under active development and the protocol, function names, settings, and defaults are still subject to change. This page documents…

The Quack protocol turns DuckDB into a client-server database.

How to download data using R

A minimal columnar query engine with lazy execution on datasets larger than RAM. Provides 'dplyr'-like verbs (filter(), select(), mutate(), group_by(), summarise(), joins, window functions) and common aggregations (n(), sum(), mean(), min(), max(), sd(), first(), last()) backed by a pure C11 pull-based execution engine and a custom on-disk format ('.vtr'). Reads and writes 'GeoTIFF' (including tiled and 'BigTIFF' layouts) and a tiled raster format ('.vec') with overview pyramids and time cubes for larger-than-RAM raster data. Streams vector operations (spatial transforms, point-in-polygon and nearest-feature joins including a two-sided grid-partitioned join, select-by-location, clip, erase, dissolve, 'rasterization', 'polygonization', and contouring) through 'sf', and runs raster operations (zonal statistics, focal windows, terrain derivatives, resample or 'reproject' warp, polygon masking, map algebra, and 'mosaicking') in native C or over the tiled '.vec' format, one batch or tile at a time for data larger than RAM.
