[R-sig-Geo] importing raster with embedded colors

[Benjamin Leutner]

If you import it as RasterBrick or RasterStack it should give you three 
RGB layers
These can then be plotted as an RGB composite:

b <- brick("your.tif")

## with raster
raster::plotRGB(b)

## or, if you prefer working with ggplot
RStoolbox::ggRGB(b, r = 1, g = 2, b = 3)

Cheers,
Benjamin
