Dear list,
I have two problems related with UK in geoR package.
Q1) I can't perform UK with a 2nd order trend. The krige.conv() and ksline()
functions reports me the same error all the time.
Q2) I can't understand how carrying out an UK with 1st order trend and choosing
moving neighborhood of
Dear list,
I have a computational error and I can not found the solution...
I would like to perform an Universal Kriging with geoR. I have a geodata
object: log(price), long, lat and pollution, but 'krige.conv' and 'ksline'
functions give me the same error: system is computationally singular.
Dear list:
I'm new in spatial panel data. I try to do a simple model but I have the
following error in splm library. Please, could you help me?

Dear list:
I'm trying to fit a spatio-temporal variogram model in gstat.
I'm reading: http://cran.r-project.org/web/packages/gstat/vignettes/st.pdf
My dataset is: CO, 23 Monitoring stations (irregular), 24 hours.
I create a STFDF object and it looks fine, but when I try to create
a variogramST,
Dear list,
I'm using the coal ash percentage data to perform a median polish kriging.
Why the the residuals are different from data-overall effect-row effect-column
effect?

coal.mat <- tapply(coalash$coalash,
list(factor(coalash$x),factor # percentages
Dear list,
I would like to know hoy to run block kriging with geoR. It is possible? What
is the function?
Thanks in advance,

the varigram distances are gruped in classes (simular to what is done with
an histogram)
ins in experimental semivariogram
Please express in R what you have done

Dear list:
I have a 5x5 regular grid 100x100. When constructing the experimental
semivariogram using gerR() I expected to have 14 different distances.
However, I obtained 10 semivariogram points corresponding to 10 bins.
- Which is exactly a bin?
- Which is the bin correspondence wiht the 14

Dear all,
first Happy 2011!
I have two diferent files:

-on the other hand different variables (*.csv or *.txt) for each district.
I would like to joint the district with its variables for study its
characteristics but
