Dear list,
Maybe someone can shed some light on this error. I have a dataset with
thousands of candidates with electoral support per city. I wrote a R script
to calculate both Moran.test and Moran.MC (9 iterations), and also
Geary C test.
The script run very fine, but at the end I have noticed

I'm new to R.
I'm trying to emulate what one would see in ERDAS feature space with two
raster layers containing different attribute data on different scales. x =
layer 1, y = layer 2; and the number of pixels (there are 3881020 total,
not all with data, what are the limits in R?) that fall within
Thanks Sarah and Robert,
The hint from Sarah worked fine, but im also going to upgrade.
Cheers

Agus,
I think you can ignore this warning, but better still would be to run
update.packages()
or at least update the raster package, as I think the warning goes away
after you do that.

Thank you! That solved it.

Dear list,
For first time after using it several times, I had warnings using the crop
function with a raster stack from soil layers in format geotiiff derived
from the HWSD.

specifically, when:

That is probably because idw.locations is not exported in the package
NAMESPACE. I would try instead:
loc.idw <- idw(value~1, NARR, loc, idp = 1.0, debug.level = 1)

Eric,
I strongly recommend "image segmentation algorithms and tools" even if
it's not necessarily a classification algorithm. Image segmentation and
tools to derive features from the segments are, for the most part,
lacking in open source software. There are some segmentation tools out
there
Thanks for the hint Tom,
I did came across this post previously:

so. Do

Hello all,
I'm looking for some feedback and ideas regarding the need to improve
image classification abilities in GRASS GIS. My understanding is that
since the required classification techniques aren't available in
GRASS, the researchers doing that work are found elsewhere. Hopefully
this is a
