What is bcdata?

The R gateway to B.C.'s data catalogue, mostly busy keeping pace with the servers behind it.

bcdata searches the British Columbia Data Catalogue and pulls records from it, including spatial layers retrieved through WMS and WFS with dplyr-style filtering translated into CQL queries sent to the server. The recent releases are small and corrective: 0.5.3 fixes malformed CQL generated by geometry predicates such as INTERSECTS, which the server had been rejecting outright, and 0.5.2 drops a leaflet extension dependency in favour of a base leaflet call. Cadence is a few releases a year.

What is jSDM?

Joint species distribution models in Gibbs-sampled C++, quiet since 2023.

jSDM fits joint species distribution models by Gibbs sampling, with the sampler written in C++ against GSL and Armadillo and exposed through binomial probit, binomial logit, Poisson log and Gaussian entry points. The 0.2 line extended it with species traits, constrained factor loadings and residual-association plots. The one entry since 2023 carries only a compare link.

bcdata vs jSDM: editorial side-by-side

B
bcdata
INFRA · APIS
0.0

The R gateway to B.C.'s data catalogue, mostly busy keeping pace with the servers behind it.

◆ Current state

bcdata searches the British Columbia Data Catalogue and pulls records from it, including spatial layers retrieved through WMS and WFS with dplyr-style filtering translated into CQL queries sent to the server. The recent releases are small and corrective: 0.5.3 fixes malformed CQL generated by geometry predicates such as INTERSECTS, which the server had been rejecting outright, and 0.5.2 drops a leaflet extension dependency in favour of a base leaflet call. Cadence is a few releases a year.

◆ Where it's heading

Almost everything in this window is a response to something changing on the other side of the connection: a CKAN 2.9 upgrade that stopped search and listing functions returning complete results, WMS and WFS capability requests that cannot be relied on, dbplyr tightening the rules for local evaluation, and general catalogue-side churn. The package's own interface has been stable since the 0.4.0 change that required local() around locally-evaluated filter calls, and the work since has gone into keeping that stable interface working rather than extending it.

◆ Prediction

Expect the same pattern: targeted fixes as the catalogue and its CKAN, WMS and WFS layers change, with occasional dependency pruning of the kind 0.5.2 did. Nothing in these entries points toward a 0.6 or a change in what the package covers.

J
jSDM
INFRA · APIS
0.0

Joint species distribution models in Gibbs-sampled C++, quiet since 2023.

◆ Current state

jSDM fits joint species distribution models by Gibbs sampling, with the sampler written in C++ against GSL and Armadillo and exposed through binomial probit, binomial logit, Poisson log and Gaussian entry points. The 0.2 line extended it with species traits, constrained factor loadings and residual-association plots. The one entry since 2023 carries only a compare link.

◆ Where it's heading

The package built out its model family quickly and then stopped: five of the six visible entries are stamped the same day as a backfilled archive, and the only later release says nothing about its contents. The direction the 0.2 line was heading, toward trait-mediated species effects and better convergence on latent variable models, has no visible continuation.

◆ Prediction

The feed does not support a confident prediction; the latest entry publishes no notes, so whether the package is still developing or only being kept CRAN-clean cannot be read from it.

Frequently asked questions

What is the difference between bcdata and jSDM?

They serve adjacent needs but don't currently overlap on shipped themes. bcdata and jSDM 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 bcdata better than jSDM?

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