Plot a mock figure with similar aesthetics to create an overall ggplot legend.
The only purpose of this code chunk is to make a simple overall legend to show that in light blue a subset of the individual permutations is shown and in purple the overall values. The original legends with permutation numbers will not be shown in the overall figure to create a cleaner look. The approach taken here was to use a simple mock ggplot figure and then use the ggpubr package to isolate the legend and display the legend together with the 4 actual plots.

Estimates of task effects for five different sample sizes (starting with \(N = 20\), then 1/5th parts of the total dataset). For each sample size 10 randomly chosen HDCI’s out of the 1000 HDCI’s computed are displayed (in light blue). The average estimate with credible interval summarizing the 1000 HDCI’s for each sample size are plotted in reddish purple. DLPFC = dorsolateral prefrontal cortex; mPFC = medial prefrontal cortex; NAcc = nucleus accumbens.

For each task, for five different sample sizes (starting with \(N = 20\), then 1/5th parts of the total dataset), the proportion of intervals not containing the value 0 is plotted in reddish purple.
