Colleagues, Thank you all for the timely suggestions. That is appreciated. What I am really looking for a way to identify difference in group level variance by using multiple comparison intervals. Minitab displays those results in a graph. This method is described in: https://support.minitab.c

Colleagues, The RVAideMemoire package has a pairwise variance test which one can use to identify variance differences between group levels. Using the example from this package, pairwise.var.test(InsectSprays$count,InsectSprays$spray), we get this output:     Pairwise comparisons using F tests
