Native interface to gdal utils
gdal_utils(util = "info", source, destination, options = character(0),
quiet = FALSE, processing = character(0),
colorfilename = character(0))character; one of info, warp, rasterize, translate, vectortranslate, buildvrt, demprocessing, nearblack, grid
character; name of input layer(s); for warp or buidvrt this can be more than one
character; name of output layer
character; raster layer read options
logical; if TRUE, suppress printing of output for info
character; processing options for demprocessing
character; name of color file for demprocessing (mandatory if processing="color-relief")
info returns a character vector with the raster metadata; all other utils return (invisibly) a logical indicating success (i.e., TRUE); in case of failure, an error is raised.
