Value
a SpatialData .zarr store of toy example data with all types of
elements represented: (multiscale) RGB image, (multiscale) label,
point, circle and (multi)polygon shape, table annotation.
In addition, all types of coordinate transformations are represented:
identity, scale, translation, affine, and sequence.
Examples
x <- file.path("extdata", "blobs.zarr")
x <- system.file(x, package="spatialdataR")
(x <- readSpatialData(x))
#> duckdb keeps downloaded extensions and secrets in a temporary directory:
#> ℹ /tmp/RtmpzeeUVM/duckdb
#> This is removed when the R session ends.
#> • Extensions are re-downloaded each session.
#> • Secrets are lost.
#> ℹ Run duckdb(shared_home = TRUE) (or create ~/.duckdb) to keep them (suitable for most users).
#> ℹ Run duckdb(shared_home = FALSE) to accept the temporary directory (and silence this message).
#> ℹ See ?duckdb_storage for details and alternatives.
