problem in Krig function of "Fields" package
hello I try to build DEM using Krig function of fields package. And I get this error message. here is the procedure I followed: > dt<-read.table("/usr/local/bartin/stat/topostat1",header=F,sep="|") > names(dt) <-c("x","y","z") > coord<-cbind(dt$x,dt$y) > elevation<-cbind(dt$z) >

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

problem installing fields package 3.5 on R 1.8.1 on linux
I am returning to using R after a little time away. Saw some great new functions in the fields package and decided to upgrade. Everything seems to go fine until I tried to actually load the package, when I get an error: >library(fields) Error in parse(file, n, text, prompt) : syntax error on line 227 And (of course) I am unable to access any of the functions in the fields package. Below is

Upgraded and authentication fails with LDAP
FreeBSD 5.2.1 Upgraded to dovecot 0.99.12.1 After authentication failed, I also upgraded OpenLDAP to 2.2.19 Dovecot and OpenLDAP are now the most recent versions in the ports. I can access the LDAP info through the OpenLDAP client without a problem, so slapd seems to be working fine. Both dovecot and OpenLDAP worked fine before the upgrade. Any help will be appreciated, since several people

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

lynx on 4.8-stable
I recently installed 4.8-stable. When running lynx, I can only access sites outside my LAN by launching lynx as root. I can't access external sites if I launch lynx using sudo or after su-ing to root. I've searched archives and googled, and haven't found anything on this. It happened immediately after the upgrade, before any post-installation configuration, i.e. before setting up

still have problem with krige and border option

Unavailable Resolutions and Falcon 4.0
I have been experimenting with getting various (usually older) D3D games running under wine and have so far been very impressed with the results - a big thank you is due to all the wine developers who have got things to this stage. With Falcon 4.0 (1.08us), however, I am stuck. The game interface works apparently perfectly, along with the background sound/music, but when I go to fly, I get black

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: Error in svd(tempM) : error 159 in dsvdc using traceback, I get: > traceback() 4: stop(paste("error ", z$info, " in dsvdc")) 3: svd(tempM) 2: Krig(x, Y, cov.function = rad.cov, m = m, decomp = decomp,

adaptive optimization of mesh size
DeaR list, I'm running an external program that computes some electromagnetic response of a scattering body. The numerical scheme is based on a discretization with a characteristic mesh size "y". The smaller y is, the better the result (but obviously the computation will take longer). A convergence study showed the error between the computed values and the exact solution

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

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.
