Transforms a matrix into a RasterLayer object.
matrixToRaster(matrix, raster = NULL, projection = NULL)A RasterLayer
a matrix object. See Details.
a RasterLayer object whose extent and projection are used to
create a raster from matrix.
a character vector providing a coordinate reference system.
Required when ncol(matrix)=3.
When ncol(matrix)=3, this function assumes that the first two
columns of argument matrix provide coordinates to create a RasterLayer,
hence argument projection must be provided. When argument matrix has
only 2 columns, then the argument raster must be provided because its
coordinates and projection will be used
to rasterize matrix.
