silhouette coefficient

KNIME Analytics Platform

Hallo,

I am searching for a node to show the silhouette coefficients.

I read a comment, that you must create a node by yourself:

Do you know an alternative way, to show the silhouette coefficients?

I appreciate your help!

I'm not aware of a way to do this with native KNIME nodes but if you put your data from KNIME to R with an R-Snippet it should be fairly straightforward.

Hey Aaron,

thanks for your help!

I will try it with your recommended way.

Could you send me the code with an example?. I'm no expert in R and with that explanation I'm not able to create the node silhouette

Thanks in advance
