[R-sig-Geo] Question on hierarchical data format 5 .h5 file format

[Michael Sumner]

try terra::rast() or stars::read_stars() on the file, both use gdal to
interrogate and read. What you get depends on the structure of the files,
variables interpreted as subdatasets. stars is more general but sees
variables as 2D arrays with bands, terra calls these bands layers.

Alternatively try raster::raster() or RNetCDF or tidync which might be more
straightforward than rhdf5 but all are quite different to each other and to
the gdal view.
