Robin! Really!!! ***Look*** at the code for your ``kdid'' function!
And look at all those bizarre plus signs!!!
They are well, plus signs. They mean ``add''.
So you're getting an expression which is syntactically valid,
but which is conceptually meaningless. And which does not define
a
Hi Robin,
I bet you are beginning with R ;-)
The problem is that you tried to reproduce even
the plus signs of the ASPP example.
Those '+' signs are printed by R at the begining
of new lines to indicate continuation of the
code, but you are not suposed to include them in your code.
You
Dear Melita,
I will try to answer your questions, but you will likely get better
feedback from the SAGA pros if you post them to the SAGA user forum on
sourceforge, see

Dear Jorge,
there are a lot of ways to do this. In straight R, here's a function designed
to work on a matrix of elevation values that I have used for many years. It is
very similar to the code you provide:
# This function calculates slope for a matrix using the Horn (1981)
# method, as
I am plotting spatial data on transparent backgrounds for overlay on top of
a GoogleMaps interface but they aren't *exactly* right.
I have set the size of GoogleMaps and my image to 640X640 and I receive
bounds information on the current region from the GoogleMaps javascript API.
The problem is
It seems that your question has nothing to do with spplot (which is a
method in package sp), as you are using plot(). If the problem is
similar to this:
plot(1:10,xlim=c(0,11),ylim=c(0,11))
par()$usr
[1] -0.44 11.44 -0.44 11.44
then it doesn't have to do anything with plotting map data, and
Thanks for that hint which pretty much solves my problem.
I am passing a spatial object to plot which is why I had thought that
spplot was ultimately called.
It appears that plot() and its parameters are in charge of setting the plot
area no matter what kind of object is passed in.

I am still having trouble with some raster overlays.
My trouble now is a result of my not really understanding how layers
and sp.layout work in the spplot function
I go through a whole mess of steps to get two rasters of identical
extent and dimension (One is a google map tile, the other my own
Dear Users,
I am trying to do a spatial Poisson-gamma model. I intend to read my data
into R then call OpenBugs/GeoBUGS/WinBugs to implement the car.normal
function.
Here is a copy for my codes:

# do Poisson-gamma spatial models using CAR
# y= number of employments x=distance to cbd
Hi Robert,
Thanks for the response. I will continue to keep forcing a write to
disk to prevent this from occurring.
Based on this post, and another earlier in the year, I looked a bit
more into other methods for calculating available RAM, at least for
Linux and Mac systems. I understand from

I've started spgrass6() with no problems but then get an error with gmeta6()
