Walks a directory of .rda files, finds every ggseg_atlas object inside
them, and rewrites their 2D geometry into the single geom slot. By default
the geometry is stored as brain_polygons (sf-optional); any legacy sf /
polygons slots are dropped. Pass keep_sf = TRUE to store the geometry as
sf instead.
Usage
migrate_atlas_files(path = "data", keep_sf = FALSE, quiet = FALSE)
Arguments
- path
Directory containing .rda files to migrate. Defaults to
"data", the conventional location in R packages.
- keep_sf
If TRUE, the geometry is stored in geom as sf. Default
FALSE — the geometry is stored as brain_polygons (sf-optional).
- quiet
If TRUE, suppress per-file status messages.
Value
Invisibly, a character vector of paths to the files that were
rewritten.
Details
Intended for downstream atlas-package maintainers across the ggsegverse
ecosystem: run once against your data/ directory, then drop sf from
DESCRIPTION Imports.
Examples
if (FALSE) { # \dontrun{
# In an atlas package, from the package root:
ggseg.formats::migrate_atlas_files("data")
} # }
