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.
What is rapr?
rapr generalises its Rangeland Analysis Platform API access one endpoint at a time
rapr pulls Rangeland Analysis Platform data into R — vegetation cover and production rasters derived from Landsat and Sentinel-2, plus the tabular summary APIs. The 1.1.3 release replaces the single-purpose table function with a general get_rap_table() covering the cover, coverMeteorology, production and production16day endpoints. The package reached CRAN in 2025 and is maintained by brownag, who also maintains the GeoPackage interface gpkg.

◆ Current state
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.
◆ 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.

rapr generalises its Rangeland Analysis Platform API access one endpoint at a time
◆ Current state
rapr pulls Rangeland Analysis Platform data into R — vegetation cover and production rasters derived from Landsat and Sentinel-2, plus the tabular summary APIs. The 1.1.3 release replaces the single-purpose table function with a general get_rap_table() covering the cover, coverMeteorology, production and production16day endpoints. The package reached CRAN in 2025 and is maintained by brownag, who also maintains the GeoPackage interface gpkg.
◆ Where it's heading
The shape is familiar for a young API client: add access to one endpoint, then generalise it once a second endpoint proves the pattern. get_rap_production16day_table() arrived in 1.1.0 and was deprecated three releases later in favour of a product argument. Between those, the work was error handling — empty geometries, server-side HTTP failures, warning timing — the unglamorous half of wrapping a remote service. The 1.0.0 release had already set the ambition by exposing both the 30m Landsat and 10m Sentinel-2 sources behind one argument.
◆ Prediction
Expect the remaining RAP endpoints to be folded into get_rap_table() as they are needed, and the deprecated 16-day function to be removed once the general interface has been out long enough.
