Please reply to the list, not just me. I've added the list address to
my own reply.

The participants in this list are happy to help with specific R
questions, as discussed in the posting guide, and ideally specific
questions accompanied by reproducible data and code, as I requested
directly and as also discussed in the posting guide.

As stated, your question is so vague that I would have to write many
pages to explain it adequately, and I'm not doing that for free. (Or
for money either; I have my own work to do.)

It's also obvious that however you were searching, you weren't doing a
very good job. Even the main R help page for, eg, kmeans() discusses
SSE, and that very quantity is returned by the function itself. Ditto
number of iterations, etc.

You need to do some work on your own before we can help you.
