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 class 'BasicRaster'
dim(x)
```

## Arguments

- x
Raster(* object

## Value

Integer or Raster* object

## Examples

```
r <- raster()
dim(r)
#> [1] 180 360 1
dim(r) <- c(18)
dim(r)
#> [1] 18 360 1
dim(r) <- c(18, 36)
dim(r)
#> [1] 18 36 1
b <- brick(r)
dim(b)
#> [1] 18 36 1
dim(b) <- c(10, 10, 5)
dim(b)
#> [1] 10 10 5
```
