plotRGB

plotRGB,RasterStackBrick-method

Make a Red-Green-Blue plot based on three layers (in a RasterBrick or RasterStack). Three layers (bands) are combined such that one is the red channel, one is the green channel, and one is the blue channel. This function could be used to make 'True (or false) color images' from Landsat and other multi-band satellite images.

methods

spatial

Reading, writing, manipulating, analyzing and modeling of
        gridded spatial data. The package implements basic and
        high-level functions, as well as map algebra. Processing of
        very large files is supported.
