Dear Experts,
My R code was perfectly working since I decide to add a 5th correlation
coefficient : hoeffdings' D.
fter a google search, I guess I need somewhere in my R code "unlist" but I
don't know where !
Here below my R code with 1 error message. At the end I get my 8 plots but they
are empty !
Many thanks for your precious help !
