Dear geostatisticans,
I'm going to deal with pretty big datasets in one of my projects (1G
pixels +), and I'd like to keep using gstat for the geostatistics.
Do someone know if the gstat package supports parralelisation of
functions like cariogram() and fit.variogram() on multicore
processors?

Walt,
You should be able to read and plot this file like this:
library(raster)
b = brick("air.mon.mean.nc", varname= 'air')
plot(b, 1)
#or
r = raster("air.mon.mean.nc", varname= 'air', band=1)
plot(r)
#or
sp = as(b, 'SpatialGridDataFrame')
#etc
The projection info is stored in r...@prj (for
Carsten,
Thanks for reporting this. I fixed the NA handling in plotRGB in
raster 1.3-1, which should be available from R-Forge later today, and
from CRAN later this week.
In stead of first reading the data with rgdal, a more direct way to
get at what you want with 'raster' is:
d1 <- stack('Hasen
Thanks Agus, I fixed this in raster version 1.3-0. Robert

Dear list members,
I'm having trouble creating a rgb color composite based one a multiple grid
object. Both the SGDF2PCT function from rgdal package and the plotRGB function
from raster package can not handle NA's. For my work it is necessary to
include No Data values for masking the study ar
Thank you for this information. I was able to reproduce the problem
even after the first dev.off().

Hello, this is just a note for new raster plotting support - and only
affects users of R for Windows in SDI mode (window application mode-
which is not the default install option). It affects both 32- and
64-bit R on Windows.
The behaviour is a bit weird and subtle, so this should only be of
