Caching

Source: R/caching.R
pg_cache.Rd

Manage cached pangaear files with hoardr

Details

The dafault cache directory is paste0(rappdirs::user_cache_dir(), "/R/pangaear"), but you can set your own path using cache_path_set()

cache_delete only accepts 1 file name, while cache_delete_all doesn't accept any names, but deletes all files. For deleting many specific files, use cache_delete in a lapply() type call
