If you landed here from an error like Library not loaded: libx265.216.dylib or
Symbol not found: _x265_api_get_216 when loading sf (or terra, gdal, anything
that pulls in libheif), this gist explains what happened, the fix that worked, and
the alternative approaches.
Full error I got:
By default, Quarto hides the table of contents (TOC) on narrow screens. This gist shows how to bring it back on mobile, drop it inline at a specific point in the page, and stop it from following the scroll — while keeping the original desktop TOC untouched.
Written up from a real fix on a Quarto HTML site with a right-hand TOC (
toc-location: right). Tested with a recent Quarto release.

| With parametrized Quarto reports, certain figures are expected to grow or shrink in widht/height based on existing data. This Quarto report demonstrates how to automatically adjust figure height based on the number of rows present in data. A horizontal column plot (where Y values are groups and X values are a continuous variable, so that bars grow sideways) of fixed height would simply shrink all columns to make them fit in the default height, but in this example, the plot height itself will increase according to the number of rows, so that all plots will have roughly the same column widths. | |
