This package contains several utility functions that I frequently use in other packages, and also miscellaneous functions that I use by myself from time to time. … The function from_root() was inspired by here::here(), but returns a relative path (relative to the project’s root directory found by proj_root()) instead of an absolute path.

Hi, It seems your problem is not in you code, but in your input. To invalidate the cache when y has changed, you may let cache_rds() know through the hash argument that y needs to be considered when deciding if the cache should be invalidated: If you do not want to provide this list of value(s) to the hash argument, you may try hash = "auto" instead, which asks cache_rds() to try to figure out all global variables automatically and use a list of their values as the value for the hash argument.
