Beginner stucked with raster + geoR package.
Hello everyone.
I am trying to build up understanding in R by trying to develop just some simple
scenarios.
I would like to explain you what I am trying to do and what I did so far.
I would like to put inside a RasterLayer (raster package) a Gaussian field (for
given covariance) using grf function (geoR package)

How to generate a random field with truncated marginal distributions?
I have asked the same question on stackoverflow but did not get a satisfying answer.
I am trying to simulate a lognormal spatial random field but I need the simulated value in a certain range. So I need some easy to use functions to generate a truncated Gaussian field to start with. To be specific, I need a function like GaussRF from the RandomFields package or grf from the geoR package to

Bug in optim - way to solve problem?
Hi,
I want to automatically fit variograms to a large number of different
sample data sets, and call the funtion "likfit" (in package geoR) from
within a for-loop. "likfit" does again call "optim". After ssuccessfully
fitting variograms to some of the data sets, the procedure crashes and I

Wine Ragnarok private server help
Been on linux (ubuntu 9.10) for about a month now. Starting to get the hang of it. The only thing from windows I am missing is being able to play this game. I've read a lot of stuff on the net and tried different things. Some say i need to trick the ip but I am unable to figure out the server IP address. A lot of private servers have certain things in place to prevent hacking, so I think

autocorrelation test
Hi all,
I would like to test the relevance of a vector field (i.e. if the
vectors are organized or not).
To do so, I would like to use an autocorrelation test, so that I have
two questions:
- is the Watson test applicable to that perpuse ?
- is the kuiper test applicable to that purpuse ?
Regards

[OT] colors in a LaTex doc
Dear R People:
I know that this is COMPLETELY off topic.
Does anyone know how to put colors into a LaTex document, please?
This is LaTex via WinEdt.
I can get colors via PcTex but not in WinEdt.
Thanks in advance!

Connection problems and weird WinSock warnings...
Hiya,
I've posted this 'enigma' on the newsgroup :

listof
Dear R developers
A question about the class 'listof', defined in package 'stats'.
Other than its definition and use in the code for 'anova',
we can't see that the class 'listof' is used for anything else
(in recommended packages, or elsewhere).
In the spatstat package we have been using a 'listof'
to represent a list of spatial objects of the same

Best way to extract values from an aov object ?
I'm trying to write a function to automate doing a variance analysis,
part of which involves doing some further calculations. The method I've
been using isn't very robust, if variable names change then it stops
working.

Can anybody tell me if there's any way to get the summarized anova

The PDF file on the web, which is an appendix on nonlinear regression
associated with the CAR book, is very nice.
When I ran through the code presented there, I found something
odd. The code does a certain model in 3 ways: Vanilla NLS (using
numerical differentation), Analytical derivatives (where the user
supplies the derivatives) and analytical derivatives (using automatic
differentiation). The
