Dear list, After one year without updates, a new version (0.17-8) of afex (Analysis of Factorial Experiments with ANOVA and Mixed Models) has finally been accepted on CRAN yesterday: https://cran.r-project.org/package=afex This new version comes with a series of new features, mostly related to mixed models, that might be of interest to some. The full list of changes can be found here: https://cran.r-project.org/web/packages/afex/NEWS The major news are: - For LMMs, mixed() now supports the Satterthwaite approximation for obtaining p-values (method="S"), via lmerTest. - mixed() methods "KR" and "S" are now obtained via tests on the full model, which can be considerably faster. - Added a new vignettes containing an extensive mixed model example analysis: https://cran.r-project.org/web/packages/afex/vignettes/afex_mixed_example.html - All arguments and slots with "." in the name have been renamed to use "_". This may lead to warnings in existing code. - Added argument all_fit to mixed(). If TRUE, each model (i.e., full and restricted) is fitted with all available optimizers and the best fit in each case selected. Can be quite helpful for GLMMs with convergence problems and method="LRT". - All returned objects ("mixed", "afex_aov", and "nice") have a pretty print() method. (Thanks to Frederik Aust) Given that I occasionally receive questions related to afex and the existing mailing list can be intimidating I have decided to establish a support forum at: http://afex.singmann.science/ Feel free to share the address with students or other interested parties. As some questions seem to repeat, I hope this can become a valuable resource. Cheers, Henrik
