duckspatial vs rpymat: at a glance
What is duckspatial?
duckspatial rebuilt itself around a lazy DuckDB class, then spent four releases filling in the geometry surface
duckspatial exposes DuckDB's spatial extension to R. In March 2026 it stopped being an sf convenience wrapper: 1.0.0 made duckspatial_df the primary class, a lazy table-like object that stays in DuckDB until explicitly materialized. Every function accepts and returns it by default, with mode = 'sf' as the opt-out. The four releases since have added roughly forty geometry functions on top of that foundation.
What is rpymat?
After three dormant years, rpymat returned to fix the OpenMP crash that breaks R and conda together
rpymat manages an isolated conda-based Python environment for R packages, providing a reproducible bridge without touching the user's system Python. It released steadily through 2022-2023 and then went quiet for nearly three years. 0.1.9 in May 2026 is the first release since, and it addresses a specific and long-standing failure mode.

◆ Current state
duckspatial exposes DuckDB's spatial extension to R. In March 2026 it stopped being an sf convenience wrapper: 1.0.0 made duckspatial_df the primary class, a lazy table-like object that stays in DuckDB until explicitly materialized. Every function accepts and returns it by default, with mode = 'sf' as the opt-out. The four releases since have added roughly forty geometry functions on top of that foundation.
◆ Where it's heading
The direction is to keep work inside DuckDB and make R the orchestration layer rather than the compute layer. 1.1.0 added macros so duckspatial functions work inside dplyr verbs; 1.1.1 moved the default to DuckDB v1.5.0 native spatial storage so CRS metadata persists in GEOMETRY columns; 1.2.0 added vector-tile output via ddbs_write_mbtiles() and the full family of geometry deserializers. Feature velocity has been high and consistent since the rewrite.
◆ Prediction
The remaining gaps are in PostGIS parity — the deserializers and tile writers landed in 1.2.0, so raster support or spatial indexing are the plausible next targets. 1.2.1 being a single message-capture fix suggests the 1.2.x line is now stabilizing.

After three dormant years, rpymat returned to fix the OpenMP crash that breaks R and conda together
◆ Current state
rpymat manages an isolated conda-based Python environment for R packages, providing a reproducible bridge without touching the user's system Python. It released steadily through 2022-2023 and then went quiet for nearly three years. 0.1.9 in May 2026 is the first release since, and it addresses a specific and long-standing failure mode.
◆ Where it's heading
The work is about surviving the seams between two runtimes. 0.1.9 addresses OpenMP double-initialization — the error users hit when R's OpenMP and conda's disagree — by setting KMP_DUPLICATE_LIB_OK as a compromise, and adds fix_omp_conflict() to symlink over conda's built-in version as the recommended real fix. The caveat is stated plainly: users must re-run it whenever R is updated, and the ABI versions must match. Earlier releases followed the same pattern, with 0.1.2 fixing segfaults from incompatible BLAS between numpy and R.
◆ Prediction
The recurring theme across releases is native library conflicts between the R and conda stacks, so further releases are likely to keep patching that surface as Python versions move. The three-year gap makes cadence unpredictable.
