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" "FRRegionNa" "ITRegionNa" "DEBioBedeu" "FRBioBedeu" "ITBioBedeu"
[15] "geometry"

> s<-sf$Unterregio
> r<-allrasters_pres[[1]]

Kind regards
Sibylle

It looks like at least one of the rasters 'r' and 's' has multiple layers. What does names(rs) return? I would offer more detailed advice, but I don't know 'raster' that well.

The "R Inferno" book [1] offers a lot of generic-R troubleshooting advice, which should help you progress past errors like this one without waiting for someone on R-help to reply.
