Kruskal Wallis does not perform post hoc analysis

Hi,

I am attempting to perform non-parametric analysis of my data but, although the platform says that the analysis has been performed and has found significant features, it does not perform/generate the post hoc analysis. The column where the significant comparison should be is full of NAs. I am having this issue on both the online platform as well as the R package.

This is stated on the ANOVA page:

“You can choose to perform one-way ANOVA or its non-parametric version (Kruskal Wallis Test). The post-hoc tests have only been implemented for parametric ANOVA.”

Oof, okay, I missed that page I guess! Thank you for your help!
