R package fillpattern by cmmr — release notes from GitHub.

Pattern fills for ggplot2, hardened against the ways users write sizes

ggplot2data-visualizationaccessibilitygraphicsr-package
◆Current state
fillpattern provides pattern fills — stripes, bricks, dots — for ggplot2 and base R graphics, aimed at figures that must stay legible in greyscale or to colour-blind readers. The 1.0.3 release is mostly defensive: size modifier strings ending in a colon no longer swap width for height, modify_size() reports invalid units instead of crashing and understands in, inches and cm, and a background colour bug in scale_fill_pattern() is fixed. The minimum R version rises to 4.2.0 for recent graphics engine features.
◆Where it's heading
Development is slow and entirely reactive to how the string-based size interface fails. The pattern across releases is the same: a user hits an edge — very small fill areas in 1.0.2, malformed unit strings in 1.0.3 — and the fix is either a graceful fallback or a clearer error. Leaning on R's newer graphics engine rather than reimplementing pattern rendering keeps the package small at the cost of raising its version floor.
◆Prediction
Expect further releases to stay in the same register: parsing and validation fixes for the size and unit interface, with the pattern set itself unlikely to change.

    Size string parsing fixed; invalid units now report instead of crash

    The parsing fixes are the substance: a trailing colon in a size modifier no longer applies the width to the height, and modify_size() handles invalid unit strings gracefully while gaining in, inches and cm. A scale_fill_pattern() background colour bug is fixed and the R floor rises to 4.2.0 for recent graphics engine features.

    Small fill areas no longer crash; min_size falls back to solid

    Fixes a crash on very small fill areas and adds min_size so those regions render as solid fills instead. A sensible degradation — a pattern in a two-pixel wedge conveys nothing anyway, and the alternative was a failed plot.

    fillpattern 1.0.1

    Lowers the installation requirement to R 4.1 for conda-forge compatibility — a packaging concession, later reversed when 1.0.3 raised the floor to 4.2.0.
