I am Bibi, a PhD student of Environmental Science in South Korea.  I am
currently writing my research paper and to deal with data I need to do Self
Organizing Map (SOM).

I am using R version 4.1.0 (2021-05-18) with kohonen package.

I was following this tutorial given

But I have a small confusion that I could not understand. To check the
efficiency of SOM model, I need to find out topographic error, which I
could not figure out.

I will be really thankful if you please tell me how I can calculate
topographic error or any alternative term or which one is the topographic
error in the given article.

Please accept my apology if I wrote or mentioned something inappropriate.

Looking forward to hearing back.

Kind regards
