What is BAS?

A Bayesian model-averaging package spending its 2.0 on memory, not methods.

BAS performs Bayesian variable selection and model averaging for linear and generalized linear models, sampling from a model space too large to enumerate. The visible history splits cleanly: 2023-2024 added sampling machinery — an adaptive independent MCMC sampler with Horvitz-Thompson estimation, hereditary-constraint counting — while 2.0.0 in late 2025 reworked how sampler output is allocated in C. The 2.0.2 patch is a PROTECT fix for rchk warnings.

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.

0.0

A Bayesian model-averaging package spending its 2.0 on memory, not methods.

◆ Current state

BAS performs Bayesian variable selection and model averaging for linear and generalized linear models, sampling from a model space too large to enumerate. The visible history splits cleanly: 2023-2024 added sampling machinery — an adaptive independent MCMC sampler with Horvitz-Thompson estimation, hereditary-constraint counting — while 2.0.0 in late 2025 reworked how sampler output is allocated in C. The 2.0.2 patch is a PROTECT fix for rchk warnings.

◆ Where it's heading

Memory is the binding constraint and the releases say so directly. The hereditary-constraint counter, the GROW option, and the replacement of over-allocation with resizing all attack the same problem: n.models is a guess, and guessing high wastes memory on problems where few unique models are actually visited. The 2.0.0 work was additionally forced by R tightening its C API against non-API calls like SETLENGTH, a constraint every C-heavy CRAN package has been absorbing. Method development has been quiet since 1.7.x.

◆ Prediction

The 1.7.5 notes call the hereditary-constraint counting a first step and say future updates will cover other constraint types, including polynomials, which remain unhandled. That is the one concrete commitment in this history, though nothing since has returned to it.

2.5

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.
