In raster: Geographic Data Analysis and Modeling

Description

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)
