What is checkhelper?

checkhelper grew from a check wrapper into a CRAN pre-submission auditor.

1.0.0 added a whole audit_* family — audit_downloads(), audit_description(), audit_dontrun() and audit_citation() — each parsing package source statically and returning a tibble of hits paired with a suggested fix. The package is now defending that position: 1.0.1 rc1 is a submission candidate answering a CRAN archival notice, after roxygen2 8.x moved DESCRIPTION's RoxygenNote field and broke a find_missing_tags() test fixture.

What is midr?

A black-box interpreter reaches CRAN, then learns multi-class and survival responses

midr explains black-box models by fitting an interpretable surrogate through Maximum Interpretation Decomposition — main effects plus second-order interactions, with exact Shapley values for the surrogate. Two months after its first CRAN release it can take a matrix response, which covers multi-class classification and survival models, and hold collections of fitted interpretations in midlist and midrib objects for comparison.

checkhelper grew from a check wrapper into a CRAN pre-submission auditor.

◆ Current state

1.0.0 added a whole audit_* family — audit_downloads(), audit_description(), audit_dontrun() and audit_citation() — each parsing package source statically and returning a tibble of hits paired with a suggested fix. The package is now defending that position: 1.0.1 rc1 is a submission candidate answering a CRAN archival notice, after roxygen2 8.x moved DESCRIPTION's RoxygenNote field and broke a find_missing_tags() test fixture.

◆ Where it's heading

The design commitment is static analysis — AST walks via getParseData(), line-by-line Rd reading, no eval() and no namespace loading — so the tool can report on a package it never runs. That commitment is what made the roxygen2 8.x break survivable: the audit pipeline itself was verified correct under 8.1.0 and only the test scaffolding had to go, now guarded by a dedicated regression test. fix_globals(write = TRUE) is being sanded down in parallel, no longer flattening per-function grouping comments or writing a degenerate empty globalVariables() shell.

◆ Prediction

The immediate move is the 1.0.1 submission itself, clearing the archival notice. Beyond that, each additional CRAN incoming-check rule remains a candidate for another audit_* function; the open question these notes still leave is whether the family ever gets a single combined entry point.

A black-box interpreter reaches CRAN, then learns multi-class and survival responses

◆ Current state

midr explains black-box models by fitting an interpretable surrogate through Maximum Interpretation Decomposition — main effects plus second-order interactions, with exact Shapley values for the surrogate. Two months after its first CRAN release it can take a matrix response, which covers multi-class classification and survival models, and hold collections of fitted interpretations in midlist and midrib objects for comparison.

◆ Where it's heading

The releases move outward along two axes at once: what can be interpreted, and how much of it fits in memory. Version 0.5.3 rebuilt the fitting path to avoid materialising large design matrices and added a save.memory option; 0.6.0 widened the response from a vector to a matrix and added parametric link functions. Class and argument names were shortened in the same release, so the package is still willing to break itself this early.

◆ Prediction

With multiple models now held in one object and visualisation methods for them, comparison across models is the surface most likely to fill out next — the collection classes exist but the notes describe manipulation and plotting rather than any comparison metric.
