What is parallelDist?

parallelDist is in pure preservation mode — one build fix every few years.

parallelDist computes distance matrices across threads in C++ via RcppParallel and Armadillo. The feature set has been settled since 0.2.3 in 2018, which added hamming distance and cosine similarity; everything after that is compatibility work. The most recent release, 0.2.7, exists only to drop a C++11 pin that newer Armadillo versions no longer tolerate.

What is rosm?

rosm 0.3.0 silently deprecates its entire API and rebuilds on wk and curl

rosm downloads and stitches raster map tiles from OpenStreetMap and similar sources for use in R. After six years without a release, 0.3.0 deprecated the whole previous API, dropped the rgdal dependency, and introduced a replacement built on wk geometry and curl's multi-download interface. The follow-up 0.3.1 is documentation and CI work, plus test skips for Bing and Stamen URLs that no longer resolve.

parallelDist is in pure preservation mode — one build fix every few years.

◆ Current state

parallelDist computes distance matrices across threads in C++ via RcppParallel and Armadillo. The feature set has been settled since 0.2.3 in 2018, which added hamming distance and cosine similarity; everything after that is compatibility work. The most recent release, 0.2.7, exists only to drop a C++11 pin that newer Armadillo versions no longer tolerate.

◆ Where it's heading

The package is being kept installable, not developed. The three most recent releases are a toolchain pin removal, a DESCRIPTION field removal, and a coercion change inherited from proxy — none originate from user-facing intent. Gaps of three to four years between releases are the norm now, and each one is triggered by something upstream breaking rather than by a roadmap.

◆ Prediction

The next release will almost certainly be another compatibility fix timed to whatever Armadillo, Rcpp or CRAN check policy changes next. Nothing in the entries points to new distance measures or API work.

rosm 0.3.0 silently deprecates its entire API and rebuilds on wk and curl

◆ Current state

rosm downloads and stitches raster map tiles from OpenStreetMap and similar sources for use in R. After six years without a release, 0.3.0 deprecated the whole previous API, dropped the rgdal dependency, and introduced a replacement built on wk geometry and curl's multi-download interface. The follow-up 0.3.1 is documentation and CI work, plus test skips for Bing and Stamen URLs that no longer resolve.

◆ Where it's heading

The package is being brought back from dormancy on modern foundations rather than extended. rgdal's retirement forced the issue, and the maintainer used it to replace the download path with concurrent curl requests and to hand geometry handling to wk. What follows is consolidation: dead built-in tile sources are being tested around rather than replaced, which leaves the source registry as the obvious unfinished edge.

◆ Prediction

The dead Bing and Stamen endpoints are currently skipped rather than fixed, so the next release most likely prunes or re-points the built-in tile source list and continues retiring the silently deprecated functions.

Frequently asked questions

What is the difference between parallelDist and rosm?

They serve adjacent needs but don't currently overlap on shipped themes. parallelDist and rosm are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.

Is parallelDist better than rosm?

Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. parallelDist and rosm are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
