Changes The trend argument in estimate_slopes() was renamed into slope. trend will remain as alias. New function collapse_by_group(), which extracts the raw data points and "averages" (i.e. "collapses") the response variable over the levels of the grouping factor given in collapse_by. Only works with mixed models. Additionally, the plot() and visualization_recipe() methods get a collapse_group argument to use this feature when adding data points to plots using show_data or show_residuals. Bug fixes Fixed issue in estimate_slope() when p_adjust = "esarey". Fixed issue in estimate_contrasts() when p_adjust = "tukey". Fixed error with truncated message when standard errors could not be calculated.
