We'll try for a third time. This has been archived 2X already. This time I just removed all caching capability and basically rewrote the whole package for a major release that breaks backward capability but simplifies using it. Now it only has two single functions, one creates a data.table the other a {terra} SpatRaster of the CRU CL 2.0 climate data either by download or from local files.

@adamhsparks what's the download format, how big is it in total and what's the update schedule?
Just, maybe time to reformat it to an updating new store rather than downloading/caching? It's a hard boundary to cross but really nice when the new store is fast and lithe
We did this with GHRSST ~8000 daily 500Mb COGs, it's also a good collective topic going fwd. We copy to source.coop, S3 or bare url. No egress cost..the lambda $ about $10 a month, but it could run on hpc/nectar.
I do that for private packages and did that for a public package: download everything, reformat/clean a bit of the stupidity, use a better format/compression, wrap in duckdb (for spatial I am excited about gdal vrt but never have a use case).
that being said I do not need to bother with CRAN and the data is not updated frequently so a random shell script do the job of all the above.
(and use objects storage)
