R devel - Jan 2012 - x11() graphic device, displaying raster

Hello,

I am wondering about the X11() graphic device on Windows. 
I try to plot a raster image but nothing gets displayed. I
found some pages where it is mentioned that x11() not
always supports raster rendering.
Is there any add on for x11, any update or any R-package
which solves that displaying problem in Windows?

What I try to test it is an example from the
package {raster}:

library(raster)
DEU_alt <- getData("alt", country="DEU", mask=TRUE)
x11()
plot(DEU_alt,axes=TRUE)

best regards,

/johannes

Try an R version that is recent - it works for me.

There is no such device: there is a function of that name as a 
convenience wrapper for windows().

I think you are talking about the X11 device on a Unix-alike, most 
likely long ago.  But for example ?rasterImage says

      Plotting raster images is not supported on all devices and may
      have limitations where supported, for example (e.g. for
      ?postscript? and ?X11(type = "Xlib")?) restricted to opaque
      colors.

'some pages' isn't good enough: do give precise references to back
up
your allegations.

That's not really the same usage of 'raster'.   But that example
works
for me (and pops up a windows() device).  It does download a data file, 
and that is often a fragile thing to do.

I used 32-bit R-patched on Windows 7, for the record.

I first tried it with R 2.13.2 and raster version 1.9-64 (16-January-2012).
Now I also installed the most recent version R 2.14.1 (Platform:
i386-pc-mingw32/i386 (32-bit)) and raster version 1.9-64 (16-January-2012).

But in both cases no success. X11() opens and draws the axis and the
border for the scale but no raster...

There is no problem with vector graphics...like:
DEU_border <- getData("GADM", country="DEU", level=1)
plot(DEU_border,axes=TRUE)

Any suggestions what is going on resp. how to solve it...?

I do not really understand why you are using x11(). The Windows device 
is called windows() and you actually do not need to open it, since plot 
opens it anyway. Or are you under cygwin (which is not really Windows)?
If not: Which version of Windows is this?
