Hello!

    I need to use Kruskal-Wallis test and post-hoc test (Dunn's test) for my data. But when I searched around, I only found this function: kruskal.test. But nothing for Dunn's test.

    So I started to write one myself.  But  I do not know how to count ties in the data frame. I can use for loops but it seems long and unnecessary since the rank function actually knows the ties. So can anyone give me a hint on how I can "count" the number of ties?

    Many thanks.
