Can I create queen or rook spatial weights with R?
Yes, see ?poly2nb in spdep.
I'm migrating from Geoda to R, is there any good introductory text for basic

Follow the technique that your code already uses (a for() loop to iterate
over a series of values, and a paste() function to generate the filename).
To be more specific:
for(method in 1:3) {

Hi all,
I wish improve this code. I have 3 raster DCM_1, DCM_2, and DCM_3 (where:
DCM= Digital Crown Model) obtained from three methodology. To apply my
analysis I wish to elevate every raster to power of 1.5 to 4.0 by 0.1.
Respect to write three times the below formula I wish to understatin
In that case, you could always try stacking the panels vertically instead of
horizontally? If this is even possible with the function you are using. Or
just plot each panel to an image and superimpose them using another method?
I've done things like that where I had R create PNG images and then c

Hi Rubén,
Try this,

Dear listers,
I met a trouble with spsample which has been solved by Roger Bivand off
list. I though it was general enough to be of interest for other users.
In brief I needed to get 50 random points on a SpatialLinesDataFrame
called "hydntline" and got:
spsample(hydntline,50,type="random")
