still have problem with krige and border option
Dear all,
I would like to estimate rainfall with the krige function. First, I produce a
polygon of my region of interest (where poly_test.txt is a x,y suite of
points defining a polygon, obtained with the grass v.out.ascii command) :
user>border_limite<-read.table("/home/lionel/rwork/poly_test.txt",header=FALSE)
user>polygone<-list(x=border_limite[,1],y=border_limite[,2])

krige and polygon limit problem
Dear all,
I'm new on R and this mailing list. We work on spatial rainfall estimation
with R and Grass.
We have a problem with the krige function from the sgeostat package. We would
like to limit the estimated area with a polygon limit.
I use a 50 points polygon to describe my work area. The krige function work
quiet well without limit. But if I use this option I have the following error

readline editor
Dear all,
I have a problem with the readline editor of R since it doesn't work.
Setting ./configure --with-readline does not the fix the problem.
Does anyone have an idea how to fix this? Many thanks in advance!

4D Plot ??
Tried to post this last night, but it doesn't seem to have appeared.
Using R 2.0.1 on Windows XP + SP2.
I am traveling, away from my usual references. I'm trying to make a
4-dimensional plot: a levelplot with overlaid contours, with different
response variables represented by (1) colors on the levelplot and (2)
the contour lines.
First try was filled.contour + contour but the key

R crashing
Hello,
This is what I am trying to do: I wrote a little function that takes
addresses (coordinates) as input, and returns the road distance between
every two points using Google Maps. Catch is, there are 2000 addresses, so I
have to get around 2x10^6 addresses. On my first go, this is what I did:

2/3d interpolation from a regular grid to another regular grid
Hello R users,
I have numerical data sampled on two grids, each one shifted by 0.5
from the other.
For example:
grid1 = expand.grid(x=0:3, y=0.5:2.5)
grid2 = expand.grid(x=0.5:2.5, y=0:3)
gridFinal = expand.grid(x=0.5:2.5, y=0.5:2.5)
plot(gridFinal, xlim=c(0,3), ylim=c(0,3), col="black", pch=19)
points(grid1, xlim=c(0,3), ylim=c(0,3), col="red", pch=19)

border of a polygon in contour.kriging - geoR
Dear all,
When a conventional kriging and then a contour plot is limited with a polygon (as possible with krige.conv and contour.kriging), the
polygon border is displayed in black by default.

Suggestion: 'method' slot for expand.grid() (incl. diffs)
Dear expeRts,
The order in which the variables vary in expand.grid() is often unintuitive. I
would like to suggest a 'method' slot for expand.grid() which requires only very
little changes (100% backward compatible) and which allows one to control this
order. Please find attached diffs against R-devel.
Cheers,
Marius

lme convergence failure within a loop
Hi R-users,
I'm attempting to fit a number of mixed models, all with the same
structure, across a spatial grid with data points collected at various
time points within each grid cell. I'm trying to use a 'for' loop to try
the model fit on each grid cell. In some cells lme does not converge,
giving me the error:
Error message: In lme.formula(logarea ~ year + summ_d, data =

[PATCH node] Introduces the virtual network administration functions.
Moved the node administration elements to a separate submenu.
Created a new network administration menu.
* users can define a network
* users can create a network
* users can destroy a network
* users can undefine a network
* users can list existing networks, including details
Each new command is also available as a separate command line executable
as well.

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

krige in gstat() package
HI,
I wonder does anyone have experience with doing sequential gaussian
simulation with krige() function in gstat?
I find it VERY slow compared to use krige() to achieve kriging function
itself.. I wonder why, is that because it has to model the variogram, and
do the kriging separately for each point to be simulated?
so it would be N times slower to achieve the simulation than the kriging

problem with glsm.krige: trendd and trend l must have similar specifications error
Hello,
I used glsm.mcmc and likfit.glsm to create model. Now I want to predict at different locations, but I can't get glsm.krige to work. I keep getting the error that trend.d and trend.l must have similar specifications. I have tried numerous ways to include the covariates in the glsm.krige model, and I keep getting the same error message. The bolded part is the part that doesn't work.

Using geoR krige.conv
Hi,
I'm using the function krige.conv from package geoR but I'm getting a
warning that I do not understand:
Warning messages:
1: NaNs produced in: sqrt(variance)
2: NaNs produced in: sqrt(variance)
I'm performimg an ordinary kriging with a log transform (lambda=0).
Does anyone knows where this comes from ?
Thanks and regards

Memory problems using Krige (sgeostat)
I?m trying to make an estimation of sea-depth for 2000 animal locations
using 2 million depth soundings. The result was:
Cannot allocate vector of size 20351 Kb
I've tried to overcome this problem by making the following adaptations.
-Increased the max-mem-size to 1.5Gb (Thanks to Thomas Lumley for his help)
-Use a max.dist (10km) for the function Krige
-Run the Krige computation for each

issues with krige function
Greetings all,
Ran into a strange problem with the krige function from geoR. The
problem that I am having is that while the krige function seems to
work well, the resulting predicted values are all NAs. Given the size
of the datasets I am working with can't attach it, but I can provide
snippets of the datasets.
