[R] Values cells

[Frede Aakmann Tøgersen]

Well, if you are using the print method on a raster object  what do you get then?

Try this:

> library(raster)
Loading required package: sp
>      logo <- raster(system.file("external/rlogo.grd", package="raster")) 
> print(logo)
class       : RasterLayer 
band        : 1  (of  3  bands)
dimensions  : 77, 101, 7777  (nrow, ncol, ncell)
resolution  : 1, 1  (x, y)
extent      : 0, 101, 0, 77  (xmin, xmax, ymin, ymax)
coord. ref. : +proj=merc 
data source : c:\Programmer\R\R-3.0.2\library\raster\external\rlogo.grd 
names       : red 
values      : 0, 255  (min, max)

See the values entry. Since this is a color image there are 3 bands. What you see above is for the first band ("red").

Going from 0 to 255 for red is no surprise. You will probably see the same for green and blue as well.

What are you really looking for?

Yours sincerely / Med venlig hilsen
