Thanks so much 🙂

I think the Cleveland data had 6 rows with ‘?’ as the value for two of its attributes. I think it was for columns 12 and 13…

For me I am having issues with the Silhouette plot but hopefully can find something out 🙂

I think the plot in 2d was what was asked for and should be good. I was searching online as to how to plot the Silhouette plot in R. The reason being that when I did my 2d plot prior to the K-means clustering, I assumed the k value to be 3, based on the plot generated before applying K-means ( just visual check). I think the Silhouette plot can help confirm if our cluster number is good.

The better the Silhouette coefficient, the better the clustering that we got. Still learning through 🙂
