Extracting Krig results
I'm new at this, so please bear with me.
I am trying to get Krig (actually tps) results into a data frame at a
set of points.
Frankly, all I really need is to query the Krig on a specific XY pair
and return a result. I can carry the rest. I am using tps from the
fields package.
Here's the code I use to create the Krig object:

Tps
Hi,
I have a 4 column file (long/lat/elev/variable) and I tried to fit the
values of my variable to the XYZ space using Tps and I keep getting the

non-stationary covariance
Hi !
Sorry for my ignorance. I have two questions:
1) which is in R the function to make a covariogram of spatial data ?
2) does anyone know if there exist the possibility in R of performing
kriging with an arbitrary covariance function ?
If I have well understood the Krig procedure offers only three
possibilities (expcov, gauscov and sphercov) that are the common models
for stationary and

Error in Fields TPS function {svd ...} again
Thanks for all the helpful responses. I include the data file and the
syntax file for reference. Again, if I use the fields function, as is, I
get the message:

geoR - help for bayesian modelling
Hi,
I am trying to do a bayesian prediction for soil pollution data above
a certain threshold, using geoR.
Everything is working fine until i am doing the krig.bayes. I tried to
do the prediction on a grid 67 by 113 cells and my computer is
freezing to death. At larger numbers of cells it tells me after a while
that it reaches the max. memory of 511 Mb. My computer has only
512 Mb of RAM.

Need help with optimizing GlusterFS for Apache
Our webserver is configured as such:
The actual website files, php, html ,css and so on. Or on a dedicated
non-glusterfs ext4 partition.
However, the website access Videos and especially image files on a
gluster mounted directory.
The write performance for our backend gluster storage is not that
important. Since it only comes into play when someone uploads a video or
image.

Plotting a kriging on a map
Hi list,
Well, this time I’ve a doubt with mapping generation.
I was already able to read and plot shapefiles, plot point on this map. All
this without any problems, but now I want to do something that I think, only
Golden Software Surfer is capable of.
I would like to plot a kriging result on the existing map (map script
below). Well I looked for on the net, but I was not able to be sure of

Help with Kriging
R Experts,
I'm looking for some help with the geoR package. I'm trying to krig
some data without using a global neighborhood. I would like to set my
moving neighborhood to a distance, say 100 meters, where I know my data
is spatially correlated. I have tried the ksline function, but that
only allows my moving neighborhood to be set to a number of data points.
But, since my data

kriging C/C++ code
Hello to everybody !
I don't have a question directly connected with R, but it takes starting
point from the use of the R function Krig for kriging interpolation and
from the idea of making a different implemetation of the function for my
purposes.
Doas anyone know where can I find free C or C++ codes of kriging ?
As always, thanks a lot in advance,
Paola.

What if geoRglm results showed that a non-spacial model fits?
Hi R-people:
Working in geoRglm, it shows me, according to AIC criterion, that the non-spacial model describes the process in a better way. It's the first time that I'm facing up to.
These are my results:
OP2003Seppos.AICnonsp-OP2003Seppos.AICsp
#[1] -4
(OP2003Seppos.lf0.p<-exp(OP2003Seppos.lf0$beta)/(1+exp(OP2003Seppos.lf0$beta))) #P non spatial

Ordinal Package Errors
I'm trying to install the ordinal package

I downloaded ordinal03.tgz and untarred it. rmutil was previously
installed (and appears to work ok.) Then I installed ordinal:

3-d kernel smooth by the "kde" function
Dear R community,
I'm having hard time to understand the kde function in "ks" package. Let me
use a 3-dimensional kernel smooth example to explain my question using the
elevation data in geoR.
### here is what I did ###

require(geoR)

elev.df <- data.frame(x = elevation$coords[,"x"], y =
elevation$coords[,"y"], z = elevation$data)

Is gluster suitable and production ready for email/web servers?
I've been leaning towards actually deploying gluster in one of my
projects for a while and finally a probable candidate project came up.
However, researching into the specific use case, it seems that gluster
isn't really suitable for load profiles that deal with lots of
concurrent small files. e.g.

problem installing packages from source on win2k
Dear R-helpers,
I'm having trouble compiling R packages from source on Win2K. I installed R 1.7.1beta [1] on my win2k machine [2], downloaded the fields package as source [3] and tried but failed to install the package [4]. I get the same problem with other packages, so it doesn't appear to be limited to fields. Installation of precompiled packages seems to work fine. I've been

assign point values as labels in spplot
In the code to follow, I'm trying to label points with their corresponding
values but have been unsuccessful after many variations to the following
code. The code below creates the plot I want, I simply cannot get the black
points ("+") to display the actual value. I'm guessing the problem is
somewhere in the second to last line of code (starts with "pts<-..."). I
