In parSim: Parallel Simulator

parSim 0.3.1

• Reduced example runtime to avoid CRAN check NOTEs.

parSim 0.3.0

Breaking changes

• The primary argument names have been restored to their original names from version 0.1.x: nCores (was cores), write (was save), and name. The new-style arguments cores and save are still accepted via ... but will produce a deprecation warning and will be removed in a future release.

New features

• Restored parSim_dt(), the data.table-based variant of parSim(). The parallel backend has been updated to use parabar (replacing snow and pbapply), while retaining data.table internals for efficient data handling.

• Added env argument to both parSim() and parSim_dt(), defaulting to parent.frame(). This fixes an issue where the export argument could not find variables defined in the caller's environment when parSim() was called from within a function (GitHub issue #10).

Bug fixes

• Fixed "no visible binding for global variable" NOTE from R CMD check in parSim_dt().

parSim 0.2.0

• Parallelization backend changed from snow to parabar.
• Progress bar support via parabar.
• Added configure_bar() function (re-exported from parabar).
• Added replications argument (deprecating reps).
• Internal refactoring to use dplyr for result handling.

parSim 0.1.5

• CRAN release.
• Added parSim_dt() function using data.table internals.

parSim 0.1.4

• Added exclude argument to exclude simulation conditions.
• Added nCores argument for parallel execution.
• Added write and name arguments for saving results to file.
