grafify v4.0 The reason this is a major update is that now ggplot2 version 3.4.0 or higher is required to avoid errors with grafify. The main difference is that size argument for line widths has been updated to linewidth. Major updates It is easier to plot 2-way ANOVA designs with or without blocking factors in this version with the following updates. There are two new plot_... functions for 1-way and 2-way designs. a. plot_4d_ functions can now plot 2-way ANOVAs even if the shapes argument is not provided. Graph is plotted with shape = 21 as default. b. plot_4d_point_sd and plot_3d_point_sd functions for plotting 2-way and 1-way ANOVAs without or with blocking factors as mean and SD/SEM/CI95 error bars. Minor updates Fixed the double {{ in theme_grafify. Added hjust and vjust arguments to theme_grafify to adjust text alignment when angles are changed. Several tests were rewritten to comply with ggplot2 update.
