fuzzy kappa

Well, I could be wrong, but I suspect, that you can try "goofcat" 
function from "ithir" package.

    According to Hagen?Zanker (2009:
    https://doi.org/10.1080/13658810802570317), ?The Fuzzy Kappa statistic
    expresses the agreement between two categorical raster maps. The
    statistic goes beyond cell?by?cell comparison and gives partial credit
    to cells based on the categories found in the neighborhood.?

    Does anyone know of a package/function to compute such a Fuzzy Kappa
    statistic in R?

    Thanks in advance,
