prism vs RMVMR
A side-by-side editorial comparison of prism and RMVMR — release velocity, themes, recent moves, and the top alternatives to consider.
prism vs RMVMR: at a glance
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.
What is RMVMR?
RMVMR is being tidied in lockstep with MVMR, the package it wraps
RMVMR provides radial multivariable Mendelian randomization — radial IVW estimation and plots layered over the MVMR package's conditional instrument-strength machinery. It has no independent release schedule: versions arrive alongside MVMR's, pin a minimum MVMR version, and fix defects in the seam between the two. Its most recent release landed the same day as new versions of MVMR and OneSampleMR.

◆ 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.

RMVMR is being tidied in lockstep with MVMR, the package it wraps
◆ Current state
RMVMR provides radial multivariable Mendelian randomization — radial IVW estimation and plots layered over the MVMR package's conditional instrument-strength machinery. It has no independent release schedule: versions arrive alongside MVMR's, pin a minimum MVMR version, and fix defects in the seam between the two. Its most recent release landed the same day as new versions of MVMR and OneSampleMR.
◆ Where it's heading
The work is code hygiene with results held fixed. ivw_rmvmr() now fits the radial IVW model explicitly rather than inheriting variables left over from the orientation loop, an undocumented data element carrying unused intermediate frames is gone, and plot_rmvmr() stops recomputing univariate radial analyses it already has — roughly halving the RadialMR calls with identical output. Each note is explicit that coefficients, standard errors and degrees of freedom are unchanged, which is a deliberate contrast with MVMR's own 2026 releases, where several fixes did change reported values.
◆ Prediction
Because the package pins MVMR versions rather than vendoring behaviour, the next release most likely follows MVMR's next correctness fix; nothing in the notes points to independent feature work.

Frequently asked questions
What is the difference between prism and RMVMR?
They serve adjacent needs but don't currently overlap on shipped themes. prism and RMVMR 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 prism better than RMVMR?
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. prism and RMVMR are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
