Convenience function that creates a new eddy or re-uses it if present.

use_eddy(eddy_name, cache = default_cache(),
  flow_options = default_flow_options(), reuse_if_present = TRUE,
  set_current = TRUE, eddy_env = default_eddy_env())

Arguments

eddy_name	Unique name for the eddy to allow retrieving later.
cache	A cache object returned by one of the cache functions.
flow_options	Options to store for future flow invocations. They do not affect the eddy, they are only stored for ease of access.
reuse_if_present	Logical, whether or not to reuse an eddy with the same name, if already present, even if the flow_options are different.
set_current	Logical, whether to make this eddy current.
eddy_env	The environment in which the eddy is put (bound).

Value

An eddy object to be used for storing flows.
