SimEngine 1.4.0
Major changes
- Substantial updates to the package documentation, including both the vignettes and the function reference.
Minor changes
- Deprecated the use of the
add_to_tid environment variable in run_on_cluster().
- Additional error handling to prevent invalid names.
SimEngine 1.3.0
Major changes
- Added an option for the
summarize() function to calculate Monte Carlo standard errors and confidence intervals for all inferential summary statistics. For summary statistics meant to estimate a population quantity (e.g., the bias of an estimator), the Monte Carlo standard error quantifies variability due to running a finite number of simulation replicates.
Minor changes
SimEngine 1.2.0
Major changes
- Added the
batch() function, which allows for sharing of data or objects between simulation replicates. Essentially, it allows you to take your simulation replicates and divide them into “batches”; all replicates in a given batch will then share a single set of objects. The most common use case for this is if you have a simulation that involves generating one dataset, analyzing it using multiple methods, and then repeating this a number of times. See the documentation for more info.
- Overhauled and simplified the interface of the
summarize() function and added several summary metrics (correlation, covariance, n_reps); see the documentation for more info.
- Users can now run multiple simulation replicates per core when running code on a CCS using
run_on_cluster().
Minor changes
- Added results of a call to
sessionInfo() to vars().
- Changed
sim_id to rep_id to avoid confusion with sim_uid.
- Removed the option for a user to specify a subset of
sim_uids.
- Removed the
keep_extra option from update_sim() and update_sim_on_cluster().
- Removed the
.add option from set_levels().
- Added a constraint to
set_levels() to prevent changing of level variables once they are initially set.
- Fixed a bug associated with functions that have a NULL environment (e.g. as.integer).
- Fixed bugs that previously prevented users from running a simulation with no levels.
- Various minor bug fixes.
SimEngine 1.1.0
Major changes
- Removed the add_* functions, as we ultimately deemed these unnecessary to the workflow:
add_creator(), add_method(), add_constants(). Instead, functions declared in the parent frame of the new_sim() call are automatically added to the simulation object. It is now recommended that simulation constants are stored and referenced in the same way as levels; see “Advanced Usage” on the SimEngine website (https://avi-kenny.github.io/SimEngine/).
Minor changes
- Fixed a bug related to the use of closures added via
add_method().
- Added more info in the documentation about how to properly load packages via
set_config() (since this was a source of confusion among some users).
- Fixed a few minor issues with the documentation.
