filtro vs prism: at a glance
What is filtro?
filtro moves to S7 and multiplies its feature-scoring methods in a single release.
filtro supplies feature-selection filter scores for the tidymodels stack. Version 0.2.0 adds five scoring methods — correlation, random forest importance, information gain, ROC AUC and cross tabulation — and moves the package from S3 to S7. It also gains a ranking layer: show_best_score_* and rank_best_score_* helpers for a single score, plus desirability-function helpers for optimising across several scores at once.
What is prism?
prism rebuilds on Oregon State's new API and starts the move to cloud-optimised GeoTIFF.
prism downloads and handles PRISM climate data in R. Version 0.3.0 rewrites the package against the API Oregon State introduced in September 2025, arriving after a gap the maintainer apologises for. Normals now download as cloud-optimised GeoTIFF rather than .bil, so helper functions such as pd_plot_slice() and pd_image() do not work with them. Archives mixing old and new API data trigger a warning and a recommendation to start fresh.

filtro
0.0ANALYTICS
filtro moves to S7 and multiplies its feature-scoring methods in a single release.
◆ Current state
filtro supplies feature-selection filter scores for the tidymodels stack. Version 0.2.0 adds five scoring methods — correlation, random forest importance, information gain, ROC AUC and cross tabulation — and moves the package from S3 to S7. It also gains a ranking layer: show_best_score_* and rank_best_score_* helpers for a single score, plus desirability-function helpers for optimising across several scores at once.
◆ Where it's heading
The package is being built out on two axes at once — the catalogue of scores, and the machinery for choosing between them. The desirability functions are the more telling half, since they assume users will filter on several criteria rather than one. Adopting S7 while still pre-1.0 suggests the object model is being settled before the API is frozen.
◆ Prediction
Expect more scoring methods on the same S7 interface and a 1.0 release once the score and ranking APIs stop moving; the ranking helpers' naming is the most likely thing to change first.
prism
0.0ANALYTICS
prism rebuilds on Oregon State's new API and starts the move to cloud-optimised GeoTIFF.
◆ Current state
prism downloads and handles PRISM climate data in R. Version 0.3.0 rewrites the package against the API Oregon State introduced in September 2025, arriving after a gap the maintainer apologises for. Normals now download as cloud-optimised GeoTIFF rather than .bil, so helper functions such as pd_plot_slice() and pd_image() do not work with them. Archives mixing old and new API data trigger a warning and a recommendation to start fresh.
◆ Where it's heading
The package is mid-migration on two axes at once: the API endpoint, which is done, and the file format, where only normals have moved to COG while everything else still fetches .bil. The stated plan is to take the whole package to COG. Until that lands, capability is split — data downloads fine, but the plotting and slicing helpers only cover the old format.
◆ Prediction
The next substantive release should extend COG downloads beyond normals and restore the helper functions against that format, closing the gap this release opened.
