Get or set the number of rows, columns, and layers of a Raster* object. You cannot use this function to set the dimensions of a RasterStack object.
When setting the dimensions, you can provide a row number, or a vector with the row and the column number (for a RasterLayer and a RasterBrick), or a row and column number and the number of layers (only for a RasterBrick)
# S4 method for BasicRaster
dim(x)Integer or Raster* object
Raster(* object
ncell, extent, res
r <- raster()
dim(r)
dim(r) <- c(18)
dim(r)
dim(r) <- c(18, 36)
dim(r)
b <- brick(r)
dim(b)
dim(b) <- c(10, 10, 5)
dim(b)
