Dear Ivan Dear community Quite nice book recommendation. Yes indeed my raster "s" (the shape file for the boxplot classes) has several layers. That's way I tried to select a layer by " s<-sf$Unterregio". > sf <- read_sf("C:/Users/....._BiogeoRegion.shp") > names(sf) > names(sf) [1] "RegionNumm" "RegionName" "Unterregio" "Unterreg_1" "ObjNummer" "Version" "Shape_Leng" "Shape_Area" "DERegionNa" "FRReg...

...ore than happy if anyone could help me. I provided codes at the end of this email.
