Matrix of xyz values in raster order.
vaster_long(dimension, extent = NULL, data = NULL, raster_order = TRUE)integer ncol, nrow
numeric extent xmin,xmax,ymin,ymax
data values
use raster order or native R matrix order
matrix of coordinates x,y
Use 'raster_order = FALSE' for traditional R matrix x,y order
