Convert a RasterStack
object where each layer corresponds to a different identifier and values
indicate the presence/absence of that category into a
RasterLayer
object containing categorical
identifiers.
category_layer(x)
Raster
object containing a multiple
layers. Note that pixels must be 0, 1 or NA
values.
RasterLayer
object.
This function is provided to help manage data that encompass multiple management zones. For instance, this function may be helpful for interpreting solutions for problems associated with multiple zones that have binary decisions.
# create a binary raster stack
x <- stack(raster(matrix(c(1, 0, 0, 1, NA, 0), nrow = 3)),
raster(matrix(c(0, 1, 0, 0, NA, 0), nrow = 3)),
raster(matrix(c(0, 0, 1, 0, NA, 1), nrow = 3)))
# convert to binary stack
y <- category_layer(x)
# plot categorical raster and binary stack representation
# \dontrun{
plot(stack(x, y), main = c("x[[1]]", "x[[2]]", "x[[3]]", "y"),
nr = 1)
# }
