# NOT RUN {
data(dems)
# finds a layer
dems[["dem_30"]]
# returns a stack
dems[[c("dem_0", "dem_15")]]
# replaces a layervalues, but not the attributes of the layer
dem2 <- dems
dem2[["dem_0"]] <- dem2[["dem_5"]]
# compare every value in the 0 and 5 ma maps, they are all the same
mean(values(dem2[["dem_0"]]==dem2[["dem_5"]]))
# }
