"How to calculate Silhouette validation for k-means using R in Rapidminer?"
I'm trying to use Silhouette validation for k-means clustering, but there's no such operator. So I'm trying to add R "execute script" operator to calculate silhouette. But I don't know much about R language. I want to calculate k-means clustering using operator in Rapidminer and only do the silhouette analysis in the R script. Does anyone know how to write such script? And how to connect the Rapidminer operator together with the R operator to make the whole process work and how the parameter keys are set? Better to make an example using XML, thank you!
