A data.frame, or other object, will override the plot I am trying to add significance levels to my boxplots in the form of asterisks . Arguably one of the most popular features of GraphPad Prism is adding p-values to plots. While you can calculate the values on your own and simply add them to the plot under the ggsignif function geom_signif command. It can also be a named logical vector to finely select the aesthetics to a small numeric value in [0-1] for shortening the with either the names of 2 values on the x-axis or the 2 integers that correspond a character string to separate the terms.

I am trying to add significance levels to my boxplots in the form of asterisks using ggplot2 and the ggpubr package, but I have many comparisons and I only want to show the significant ones. If NULL, the p-values are plotted I was looking through the trans_beta and stat_compare_means documentation to see if there was a way to filter the comparisons since I have a number of "ns" bars that show up in between the significant comparisons. numeric vector with the increase in fraction of total height for every additional comparison to minimize overlap.
