[R] problem with plotting clustered data with convex hull using ggfortify

Re: [R] Some code to run Hutcheson t-test using R

Dear Luigi: no, µ1µ2 is not "missing" First, it should actually be "µ1 - µ2". And as your usual null-hypothesis when comparing h1 and h2 is that they are not different (i.e. µ1 = µ2), the latter term adds up to 0 and may be omitt
