Dimensions of a Raster* object

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)

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
