writeFormats function

File types for writing

List supported file types for writing RasterLayer values to disk.

When a function writes a file to disk, the file format is determined by the 'format=' argument if supplied, or else by the file extension (if the extension is known). If other cases the default format is used. The 'factory-fresh' default format is 'raster', but this can be changed using rasterOptions.
