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.
