Dear 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 http://rstudio-pubs-static.s3.amazonaws.com/437468_136a369149e24f24a4d0c152860ab4c3.html . 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 Bibi [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
