For comparing two non-normally distributed samples, Leech (2002) suggested
to report nonparametric effect size indices, such as Vargha & Delaney's A or
Cliff's d. I tried to search the R-sites, but could not find related
procedures or packages that include nonparametric effect sizes.
Thank you for your help!
