I have created multiple correlational matrices for age ranges (e.g. 1-5, 5-10, 10-15 years old). However, when I do hierarchical clustering using ggcorrplot for example, running ggcorrplot(corr_age_1_mat, hc.order = TRUE) for plotting, the clustering order obviously changes if I do this separately per correlational matrix. Is there a way to keep to a standard order across plots while still employing some sort of clustering? Or perhaps adhering to one select "best" order?
For instance, the image below:
