sjstats: Statistical Functions for Regression Models.

General

• Revised help-files for r2() and icc(), also by adding more references.

New functions

• re_grp_var() to find group factors of random effects in mixed models.

Changes to functions

• omega_sq() and eta_sq() give more informative messages when using non-supported objects.
• r2() and icc() give more informative warnings and messages.
• tidy_stan() supports printing simplex parameters of monotonic effects of brms models.
• grpmean() and mwu() get a file and encoding argument, to save the HTML output as file.

Bug fixes

• model_frame() now correctly names the offset-columns for terms provided as offset-argument (i.e. for models where the offset was not specified inside the formula).
• Fixed issue with weights-argument in grpmean() when variable name was passed as character vector.
• Fixed issue with r2() for glmmTMB models with ar1 random effects structure.
