This is reflected in the second plot - the box plots have been re-arranged to ascend. Thus, the order of the levels of delay_cat will now reflect ascending median CT values of each delay_cat group’s median CT value. In the second example, the delay_cat column (mapped to the x-axis) has been wrapped in fct_reorder(), the column ct_blood is given as the second argument, and “median” is given as the third argument (you could also use “max”, “mean”, “min”, etc). You can see the box plot heights are jumbled and not in any particular order. In the first example below, the default order alpha-numeric level order is used. We want to order the box plots in ascending order by the group median CT value. Box plots show the CT value distribution by delay_cat group. In the examples below, the x-axis is delay_cat, and the y-axis is numeric column ct_blood (cycle-threshold value). Visually, this can result in pleasing plots where the bars/points ascend or descend steadily across the plot. ![]() ![]() You can use fct_reorder() to order the levels of one column by a summary statistic of another column. 46 Version control and collaboration with Git and Github.33 Demographic pyramids and Likert-scales.19 Univariate and multivariable regression.
