The 4.4.0 release of simmer, the Discrete-Event Simulator for R, is on CRAN. This update stabilises a new pace of a couple of new releases per year, which is more appropriate given the maturity that the project has reached.
This release brings us a dozen bug fixes and improvements, including the unification of the leave
/renege
API, further enhancements of convenience function to set up generators, and performance improvements for the simulation environment definition thanks to the vectorisation of add_resource
and add_generator
. See below for a complete list of changes.
New features
- Add
out
andkeep_seized
parameters toleave()
with the same behaviour as inrenege_in()
andrenege_if()
. Code and documentation of these functions are now integrated underhelp(renege)
(#208, #217). - Convenience functions
from
,to
andfrom_to
accept dynamic parameters for argumentsstart_time
,stop_time
andevery
(#219). - Activities to interact with sources have been vectorised to modify multiple sources at once (#222).
- Several generators or resources with the same parameters can be added with a single call to
add_generator()
andadd_resource()
respectively if a vector of names is provided (#221).
Minor changes and fixes:
- Fix
get_mon_*()
dispatch for named lists (#210). - Get/put the RNG state when random numbers are required in the backend (#218).
- Fix convenience functions
from
,to
andfrom_to
to preserve the environment of the supplied functions (as part of #219). - Documentation improvements (#212, #220).
- Fix queueing in multiple resources after preemption (#224 addressing #206).
