"One-way ANOVA" Bug?


If I run a "One-way ANOVA" with a grouping column (Winner Cluster) containing only one item I get this error.

ERROR     One-way ANOVA                      Execute failed: degrees of freedom (0)

As you can see in the example attached, If I remove  Winner Cluster with only 1 item,  "One-way ANOVA"  works.

Is it a bug? (If I do the same Anova using Rsnippet, it works but I'm not able to extract the result to the following node).
