Help with Krige.conv using linear models
A majority of my data makes a kriged map perfectly using an exponential
model for the semivariogram to fit my data and then going through the
commands variofit() to define the model and then krige.conv() to use the
model to predict values in a grid. But?one set of my data appears to be
linearly correlated for the first 5000 meters and not correlated beyond
that. I have been having problems

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

R version 3.3.2, Windows 10: gstat package: Error in fitting a variogram model using 'fit.variogram' function
Dear Members,
I am trying to fit a variogram model using fit.variogram function from the gstat package. The figure showing my experimental variogram can be seen here: https://i.stack.imgur.com/UZXw4.png
My code line for this operation is:
> c2.vgm.fit<-fit.variogram(c2.vgm.exp,vgm(nugget=0, psill=400,model="Exp",range =40000),fit.method = 7)
The system throws following error

geoR, plot of variog4 lines incomplete
I'm using R for Mac OSX version 1.14 (2129) and the geoR package
version 1.6-5 (the current version in the R repository). I'm running
R in OS 10.4.6 on a Mac G4 iBook (933MHz, 640 MB DDR SDRAM). I
searched the R archive and did not find a posting on this issue.
I want to use the variog and variog4 functions of geoR to
characterize the pattern of spatial autocorrelation of tree

Suppressing error messages in a for loop
Hi,
Is there any way that I can supress error messages so that they don't stop
for loops running?
I'm using the gstat package and have created a variogram model for the
double exponential model:
"dexp <- vgm( .5, "Exp", 10,.1, add.to = vgm(.5, "Exp", 100))"
and fitted it using
"dexp.fit <- fit.variogram(temp2, dexp, fit.method=6,

variograms and kriging
Hello
Trying to develop variograms and kriged surfaces from a point file. Here is
what I've done so far.

Cokriging
Dear All,
I run following code to estimate the blocks using cokriging ( my data set has more than 50,000 data points). All the things run finely but Once I run the predict.gstat function it gave the error message - "memory.c", line 58: can't allocate memory in function m_get(). I run this code on LINUX sever but result is same. Would any one please be able to give a solution for

plot() and Jpeg() increase font size and resolution
Dear list,
I am having troubles increasing the fontize when plotting a
variogram{gstat} and its model (vgm) with plot and using jpeg(). Also
the resolution in the jpeg call does not work. I am using R2.4 on
Mandriva 10.2 linux.
I can change fontsize with cex.axis in a normal plot, so I presume it
has to do with plotting the variogram model. Any help on how to increase
the font size and

Adding 3D points
I would like to add individual points and lines to a persp()
plot that I generated with the geoR package. It is a kriged
surface map of a field plot and I'd like to overlay my
sampling points on it but am having some trouble. I loaded
the scatterplot3d package, but I can't seem to use the add
parameter with it. Any suggestions?

If you are getting "login with invalid or missing password" it means one of
a few things :
* you have not selected Icecast2 as the server type in the DSP config
* you are not using the most current versions of both icecast2 and oddcast
(http://www.oddsock.org/icecast2 for that)
* you are using the most current oddcast, but have <icylogin>1</icylogin>

Settings ACLS from Windows via member server
I have a purely samba domain: samba PDC, BDC, and a collection of
clustered member servers that provide CIFS access to our underlying file
system. Things are working fine, with the exception of users being able
to set ACLS from Windows workstations. When they try to do so, they can
search for and properly find domain members, but when they try to apply
the changes, the settings simply vanish

Sale plano sí.
Ya se que sin tener los datos y el código es un poco difícil, pero es que mis datos ocupan mucho, es imposible.
Seguiré mirando por internet.
Muchas gracias Rubén.

geoR size limit problem
Hi all,
I tried to produce some kriged surfaces with geoR (latest version). The size
of the grid should be around 900 x 650 cells (what I find is not a very big
grid), and the number of points is around 2500. The command krige.conv
stopped after arround 5 min saying it can not allocate a vector with around
1.5 billion units. Sounds reasonable.
Is there a workaround? How would I partition the

Variogram fitted by Cauchy
Hi
I'm using R(2.9.0) and gstat package under Windows to plot sample variograms.
When I want to fit them, I don't have the possibility to choose Cauchy functions. Under Mathematica for example, we have it and it seems to be the best one to fit the variograms I have
I tested the others functions, they can fit but I would,if possible, use the Cauchy one. If anybody knows something about

REML option in gstat
Hi, please help!!
I've been trying to fit variogram models using the REML method in the gstat
package. Every time the Windows GUI crashes. For example
library(gstat)

x <- variogram(zinc ~ 1, ~x + y, meuse)
v <- vgm(140000, "Sph", 800, nug = 10000)
plot(x, model = fit.variogram(x, model = v, fit.method=5))
Other fit methods are non problematic (eg. fit.method=7

new gstat version
Soon on CRAN a new version of package gstat will emerge, which
has a few minor changes and possible incompatibilities w.r.t. the
previous version(s).
The new gstat (0.9-23) now:
+ depends on sp, and uses internally with Spatial* classes from sp
if data are provided in the old-fashoned way (as data.frame)
+ has a vignette to get you started with the classes in sp
