Details

caladaptr has the ability to store copies of objects downloaded from Cal-Adapt. An example of this would be the raster series data catalog and the geometries of AOI Presets.

NOTE: In general caladaptr does not cache climate data fetched from Cal-Adapt. Every time you call a function that fetches data (e.g., ca_getvals_tbl), data is retrieved fresh. The exception to this is ca_getvals_db, which has arguments you can pass to cache retrieved values into a local SQLite database to explicitly avoid downloading data twice.

The default location for the cache directory is given by R_user_dir("caladaptr", "cache"). A custom location can be set with ca_setcache.
