logr vs revdbayes

logr vs revdbayes: at a glance
What is logr?
A SAS-style logging package for R, shipping small and slowly by design.
logr produces SAS-style log files for R scripts, and is one component of the r-sassy suite aimed at analysts migrating clinical and pharmaceutical workflows off SAS. Release notes are terse — often a single line — and the cadence has thinned considerably, with one release in 2026 following a long gap. The functionality visible across this window is essentially complete: handlers, suspend and resume, explicit log_info/log_error/log_warning entries, and console output.
What is revdbayes?
Extreme value sampling in pure upkeep mode, mostly answering to Rcpp and CRAN.
revdbayes performs Bayesian extreme value analysis using ratio-of-uniforms sampling, giving random samples rather than MCMC chains. Every entry in the visible window is filed under bug fixes and minor improvements. The most recent, 1.5.7, strips missing values before fitting the generalised Pareto MLE; the two before it are an Rcpp compatibility patch and a response to CRAN check failures that turned out to be false positives.

logr
2.5ANALYTICS
A SAS-style logging package for R, shipping small and slowly by design.
◆ Current state
logr produces SAS-style log files for R scripts, and is one component of the r-sassy suite aimed at analysts migrating clinical and pharmaceutical workflows off SAS. Release notes are terse — often a single line — and the cadence has thinned considerably, with one release in 2026 following a long gap. The functionality visible across this window is essentially complete: handlers, suspend and resume, explicit log_info/log_error/log_warning entries, and console output.
◆ Where it's heading
The arc runs from correctness work on warning and error capture toward giving users control over where log output goes and how it is formatted. Recent releases are refinements of message content rather than new logging concepts, which is what a package settling into maintenance looks like. Nothing in these entries suggests an expansion of scope beyond the SAS-log-emulation brief.
◆ Prediction
Expect continued low-volume maintenance releases refining message detail and integration with the rest of the r-sassy suite, rather than new logging capability.
revdbayes
0.0ANALYTICS
Extreme value sampling in pure upkeep mode, mostly answering to Rcpp and CRAN.
◆ Current state
revdbayes performs Bayesian extreme value analysis using ratio-of-uniforms sampling, giving random samples rather than MCMC chains. Every entry in the visible window is filed under bug fixes and minor improvements. The most recent, 1.5.7, strips missing values before fitting the generalised Pareto MLE; the two before it are an Rcpp compatibility patch and a response to CRAN check failures that turned out to be false positives.
◆ Where it's heading
The methods are settled and the release traffic is external: Rcpp issues, CRAN platform checks, documentation anchor requirements. Two of the six releases exist only because CRAN's check farm flagged something, and one of those flags resolved itself. Sibling package profileCI from the same maintainer has been more active, which suggests attention has moved to newer work rather than away from R entirely.
◆ Prediction
Expect further small releases driven by Rcpp or CRAN check changes rather than by the sampling methods.
