Decompose total effects into direct and indirect paths through mediators using mediation, CMAverse 4-way, HIMA/HIMA2 high-dimensional, BAMA, two-step / MVMR mediation, or double-ML medDML. Use when testing whether a molecular phenotype (expression, methylation, protein) mediates a treatment-outcome relationship, decomposing exposure-mediator interaction via VanderWeele 4-way, screening high-dimensional EWAS mediators, or running MR-based mediation when sequential ignorability is implausible.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

## Version Compatibility

Reference examples tested with: R 4.3+, mediation 4.5.0+, CMAverse 0.1.0+ (GitHub `BS1125/CMAverse`), HIMA >= 2.3.0 (GitHub `YinanZheng/HIMA`; archived from CRAN 2026-07), bama 1.3+, causalweight 1.0.5+ (medDML), MVMR 0.4+, TwoSampleMR 0.6+, EValue 4.1+, gesttools 1.3+, ipw 1.0.11+.

Before using code patterns, verify installed versions match. If versions differ:
- R: `packageVersion('<pkg>')` then `?function_name` to verify parameters
- HIMA must be pinned at `>= 2.3.0` for the code patterns below; the formula interface `hima(formula, data.pheno, data.M, mediator.type, penalty, ...)` was introduced in 2.3.0. On HIMA 2.2.x the classic engine is the top-level `hima(X, Y, M, COV.XM=, COV.MY=, Y.family=, penalty=)` (positional order X, Y, M) with no formula interface; HIMA 2.2.x is NOT API-compatible with the examples here.
- In 2.3+ the classic engine is `hima_classic(X, M, Y, COV.XM=, COV.MY=, Y.type=)` (positional order X, M, Y; outcome type via `Y.type`, not `Y.family`); use it only to reproduce the original 2016-2021 SIS+penalty pipelines.

How to install

The exact contents, by fingerprint
mdr add pku-yuangroup/openai4s/bio-causal-genomics-mediation-analysis@sha256:40bbd1e8b3fe4761

The line at the top of this page pins the label git:20260821.2d1b678, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
