I second that - it provides the most consistent way of storing information permanently.
I was in a similar situation, and ended up using the function at https://github.com/Exp-Micro-Ecol-Hub/dmdScheme/blob/master/R/cache.R <https://github.com/Exp-Micro-Ecol-Hub/dmdScheme/blob/master/R/cache.R> And the location `rappdirs::user_config_dir(appname = "dmdScheme", appauthor = "dmdScheme”)` as the permanent cache. I either either - use a temporary cache if the cache does not exist - if the cache does exist, use that one, and - use the `createPermanent` argument to create the cache so that it can be used.
