This will be used internally if options("reproducible.futurePlan" = TRUE). This is still experimental.

Arguments

written

Integer. If zero or positive then it needs to be written still. Should be 0 to start.

outputToSave

The R object to save to repository

cacheRepo

The file path of the repository

userTags

Character string of tags to attach to this outputToSave in the CacheRepo

drv

an object that inherits from DBIDriver, or an existing DBIConnection object (in order to clone an existing connection).

conn

A DBIConnection object, as returned by dbConnect().

cacheId

Character string. If passed, this will override the calculated hash of the inputs, and return the result from this cacheId in the cacheRepo. Setting this is equivalent to manually saving the output of this function, i.e., the object will be on disk, and will be recovered in subsequent This may help in some particularly finicky situations where Cache is not correctly detecting unchanged inputs. This will guarantee the object will be identical each time; this may be useful in operational code.

linkToCacheId

Optional. If a cacheId is provided here, then a file.link will be made to the file with that cacheId name in the cache repo. This is used when identical outputs exist in the cache. This will save disk space.
