Dear List and Andrey and Paulo You might like to look at the Fuzme package at this link http://smartdigiag.com/software/#s-4.
The notes on it say: /Fuzme is an R package for calculation of Fuzzy k-means with/without extragrades. I wanted to integrate fuzzy-k means into my R workflow so i translated some of Budiman Minansy’s matlab code into R. The R version of Fuzzy k-means with extragrades is a little buggy. The FuzME <http://sydney.edu.au/agriculture/pal/software/fuzme.shtml> software is more stable and efficient. I would recommend using that for most things. If you are trying to embed the classification into your R workflow though, the R packages is OK, but not as computationally efficient. I am working on it when i can./ regards David On 24/11/2021 10:03 pm, David Hine (L WM) wrote: > Hi Andrey and Paulo > I reached out to the author of ithir package for his current advice.
