bittermelon is growing from binary bitmaps toward greyscale and color glyphs
A side-by-side editorial comparison of ardlverse and gridpattern — release velocity, themes, recent moves, and the top alternatives to consider.
An outside audit against Stata found seven errors in ardlverse's panel estimator, including regressions with no intercept.
A small R package for autoregressive distributed lag models, with only three releases on record. The first two were administrative — a CRAN version note and a Zenodo metadata update. The third, 2.0.0, is a correction release built entirely from an external audit of panel_ardl() against Stata's xtpmg, and it is the only entry here with substantive content.
gridpattern keeps widening its catalogue, and the newest patterns finally use the device's own line rendering.
An R package supplying pattern fills for grid graphics — stripes, weaves, polygon tilings, images and placeholders. Releases are infrequent and irregular, roughly one or two a year with an eighteen-month gap before the most recent. The work divides between adding pattern types and making the existing ones behave consistently, particularly around units and how spacing parameters are interpreted.

The package's direction is now set by verification against an established reference implementation rather than by feature work. The seven fixes bring panel_ardl() into strict alignment with the original Pesaran, Shin and Smith framework, and the most serious of them is structural: internal regressions used lm.fit(), which unlike lm() does not append an intercept, so every short-run regression across the PMG, MG and DFE estimators was forced through the origin. Design matrices now carry a column of ones and DFE reconstructs the grand-mean intercept to match standard fixed-effects output.
Expect the next releases to extend the same audit approach to the remaining estimators, since a package that has been validated against xtpmg on one function invites the same question about the rest.

Two long-running efforts are visible. The first is unit consistency: v1.2.1 gave the geometry patterns a units parameter, v1.2.2 extended it to weave and fixed polygon tiling to respect it — the slow propagation of one design decision through a family of functions. The second is integration with R's own graphics capabilities, which reaches its clearest expression in v1.4.2's line pattern: rather than filling bands with solid colour as stripe does, it draws stroked lines through the device, so every built-in linetype including dotdash, twodash and custom hex specifications works. The package is also visibly maintaining its external dependencies, having rotated placeholder image services as hosts disappeared.
Expect further pattern types and continued propagation of the units parameter to any function still missing it; the entries give no indication of a change in the package's scope beyond pattern fills.
