Hi,
I've tried with the names of the column but don't work:
> data_6SV_cluster
cluster intercept coefficient
1 1 -0.04436168 1.286019
2 2 -0.04415990 1.283883
3 3 -0.04414168 1.286019
4 4 -0.04375406 1.280874
5 5 -0.04400495 1.281942
6 6 -0.04390901 1.282816
> as.matrix(raster_cluster)
[,1] [,2] [,3]
[1,] 1 2 3
[2,] 4 5 6
> colnames(data_6SV_cluster)
[1] "cluster" "intercept" "coefficient"
> subs(raster_cluster,data_6SV_cluster,which="coefficient")
