SimuRg 0.2.0 (2026-05-19)

Bug fixes:

• problems in sg-translator() were solved [SD-1434]
• Replaced direct manipulation of .Random.seed with withr::with_seed() to avoid modifying the user’s global RNG state.
• Added on.exit() calls in all cases where user options or settings are temporarily modified
• Removed all \dontrun{} statements from examples. Examples requiring more than 5 seconds were changed to \donttest{}.
• No DOI or URL were added to the DESCRIPTION file, as no suitable references are available.
• Replaced all uses of T and F with TRUE and FALSE.
• Removed the phrase "Tools for" from the package description.
• Exported sg_sim_tp()
• Replaced cat() and print() calls inside package functions with message(), warning(), or stop() where appropriate.
• Removed default output paths from function arguments, including uses of getwd()

SimuRg 0.1.11

New features:

• sg_fit() now can work with covariates
• sg_converter() weighted residuals reading from monolix was added, if avaliable[SD-1391]

Bug fixes:

• problems in sg-gof-tp() were solved [SD-1458]

Documentation:

• sg_vpc_vis() documentation was fixed with the bug [SD-1361]

SimuRg 0.1.8

New features

• sg_converter() now returns two objects: GFO - generalized fit object with fit results and GCO - generalized control object, that contain information about the fit options and see the

Bug fixes

• sg_gof_res() was fixed with the [SD-1391] support request
• sg_covsens_sim() was tested on additional projects

Documentation

New features

• sg_globalsens_vis() function was added to the package

Bug fixes

• sg_converter() error with correlations between random effects [SD-1340] has been solved
• sg_converter() error duplicated DVID columns was solved [SD-1354]. Now the package compares the column names in the initial dataset and the ones specified in headers to resolve possible conflicts.
• sg_converter() error in dataset column names resolved [SD-1355]. Now the columns of the initial dataset are renamed after loading: all special signs in the column names are replaced with _

Documentation
