Details

The function first checks if the 'rb3.cachedir' option is set. If not, it uses a subfolder in the temporary directory. It creates the main cache folder and the three subfolders if they don't already exist, then stores their paths in the rb3 registry.

The cache structure includes:

• raw folder - for storing raw downloaded data

• db folder - for database files

options(rb3.cachedir = "~/rb3-cache")
