Visualizing cluster distance

SAS_ASS — Tue, 26 Feb 2019 11:18:57 GMT

Hey There!

Im conducting a cluster analysis in SAS. However, I dont really like the plot of the cluster distance.

Is there a possibility to load the the cluster results or a workflow result from the system in r to visualize the cluster distance based on the two principal components as decribed in the following article:

Thanks and kind regards!

You didn't say which visualization you're looking at or what you don't like about it, but you can definitely create just about anything you want with PROC SGPLOT if you have the data. Based on your query, check out this blog post. But if you have further questions, add some sample data/code and other can probably help.

Thanks for your answer. The type of visualizaion I want is described in the article in my post.

It is based on the two principal components and the dots visualize the cluster

I saw that and that's why I recommended the post that I did, as it had this example from PRINCOMP. Many SAS/STAT procedures offer built-in plots that might come close to what you need. But where they fall short, we have PROC SGPLOT to create customized charts.

Looks like you're looking for something like this -- which is definitely possible from SAS with SGPLOT.

You might also be interested in this post that shows a similar technique, but with prediction ellipses. If you can supply sample data, I'm sure that someone can provide or point you to a code example.
