b3doc vs portfoliobacktest: at a glance
What is b3doc?
A small B-Cubed utility for turning R Markdown into publishable docs
b3doc converts R Markdown to Markdown and rewrites front matter for documentation published by the B-Cubed project, which is its entire remit. Three releases exist: the initial pair of functions, a generalisation of the front-matter replacement, and a hardening pass that removed regex from the replace argument and standardised figures at 300 DPI. It sits in the b-cubed-eu family alongside impIndicator and shares contributors with the wider Belgian biodiversity tooling group.
What is portfoliobacktest?
Four dormant years end with a test fix, not a feature
portfolioBacktest runs portfolio strategies across multiple datasets and resampled windows, producing performance tables, leaderboards and charts. After a run of substantive releases through 2021 and early 2022 it went quiet for four years. The May 2026 release does one thing: fix unit tests against a breaking change in PerformanceAnalytics::Return.portfolio(), which now returns results for the full input series rather than only from the first weight date.

A small B-Cubed utility for turning R Markdown into publishable docs
◆ Current state
b3doc converts R Markdown to Markdown and rewrites front matter for documentation published by the B-Cubed project, which is its entire remit. Three releases exist: the initial pair of functions, a generalisation of the front-matter replacement, and a hardening pass that removed regex from the replace argument and standardised figures at 300 DPI. It sits in the b-cubed-eu family alongside impIndicator and shares contributors with the wider Belgian biodiversity tooling group.
◆ Where it's heading
The direction is toward predictability over flexibility. The replace argument arrived in 0.2.0 generalising the earlier logo-specific behaviour, then 0.3.0 pulled regex support back out of it because escape characters and over-broad matches caused unintended edits. That is a maintainer choosing a narrower tool that fails obviously over a general one that fails quietly — a reasonable trade for a package that rewrites files in place.
◆ Prediction
Expect continued small releases driven by the documentation pipeline's needs, with output-quality defaults and front-matter handling the likely subjects rather than new functions.

◆ Current state
portfolioBacktest runs portfolio strategies across multiple datasets and resampled windows, producing performance tables, leaderboards and charts.

The May 2026 release does one thing: fix unit tests against a breaking change in PerformanceAnalytics::Return.portfolio(), which now returns results for the full input series rather than only from the first weight date.
◆ Where it's heading
The development work is behind it. The 2019 to 2022 releases built the substance — parallel execution, resampling that works beyond stock data and beyond daily bars, transaction-cost-aware designs through w_current, and a switch from compounded to uncompounded returns in the Sharpe and annualized return calculations. Since then the package has moved only when a dependency forced it, and even then only far enough to keep the tests green.
◆ Prediction
Nothing in the entries suggests planned work; the next release is most likely triggered by another dependency change, on the same four-year-gap pattern.
