These options will be used on objects of class 'raster'.
Usage
opts_raster(constructor = c("as.raster", "next"), ...)Details
Depending on constructor, we construct the object as follows:
"as.raster"(default): We build the object usingas.raster()on a character matrix of colors."next": Use the constructor for the next supported class. Call.class2()on the object to see in which order the methods will be tried. This will usually be equivalent toopts_matrix("matrix"), note that the colors of a raster are stored row by row.
