Get or set the colortable of a RasterLayer. A colortable is a vector of 256 colors in the RGB triple format as returned by the rgb function (e.g. "#C4CDDA").
When setting the colortable, it is assumed that the values are integers in the range [0,255]
Usage
colortable(x)
colortable(x) <- value
Arguments
- x
RasterLayer object
- value
vector of 256 character values
Examples
r <- raster(ncol=10, nrow=10)
values(r) <- sample(0:255, ncell(r), replace=TRUE)
ctab <- sample(rainbow(256))
colortable(r) <- ctab
plot(r)
head(colortable(r))
#> [1] "#FF0036" "#AF00FF" "#00FF5E" "#FF6000" "#F100FF" "#00FFF3"
