Hello, I am presently trying to get a feel for the various packages out there that allow me to both analyze and simulate random fields. The package RandomFields is nice, but there are still a few aspects of its implementation that are confusing to me and I was hoping someone could help clarify things for me. It could also be that my questions reflect a lack of knowledge pertaining to random fields in general and not the RandomFields package specifically, i...

Hi, I'm having some difficulty installing the RandomFields package in R 1.7.0 under FreeBSD. I've installed the geoR package with no difficulties.

Not really a bug (I eventually discovered), but ... When running GaussRF()/DoSimulateRF() with n>1, the default pch="!" prints backspaces to the terminal, which causes problems (LaTeX barfs) if you're running this within an Sweave() job. Setting RFparameters(pch="") fixes the problem. Could put this in the documentation, but I don't know where you could

Dear List I am using the RandomFields package, and I have a problem when 2d-kriging, with an anisotropy, some values from an irregular network. It works well when : - 2d-kriging, without any anisotropy, some data from an irregular network - 2d-kriging, with and without anisotropy, some data from a regular network - 3d-kriging, with and...

Hi, I'm using RF to simulate a correlated variable with GaussRF set.seed=1 GaussRF(sim.kfinegrid, grid=F, model="exponential", param=c(0,0.5,0,0.2)) However when I simulate again using the same random seed I get different results. > set.seed=1 > summary(GaussRF(sim.kfinegrid, grid=F, model="exponential", param=c(0,0.5,0,0.2))) Min. 1st Qu.

Hello I am trying to install the RandomFields package by using install.packages("RandomFields") but the process fails. I think that if I pass to the g++ compiler the -lgfortran option might work. Could you please help me do this? I would like to thank you in advance for your help Best Regards Alex [[alternative HTML...

i played around and i get the hang of save and load. I just have two final questions : 1) is loading the RandomFields package the only way to check if a file ( created through the save function ) is out there or not ? Because, I generally won't know if one has been created yet or not. 2) Suppose, you have the case where you created and saved a file. When you do an ls() without loading that file, it doesn'...

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) 1. First I created a Raster Layer object r <- raster() # Default values are

...hat it is even deeper, namely that your system does not support 3GB for one pointer. (My own supports about 1.8 GB, but I never met your problem, since my needs have been more moderat (0.1 GB)). I suggest to write to the R-help mailing list, mentioning the above problem. If solved then I can check RandomFields .

I have tried to install the package RandomFields (using the packages menu) from CRAN and it fails to open the zip file. I then tried downloading the package from the author's site, but it still fails to install. Anyone had any success with this? Or am I doing something wrong. Thanks in advance for any help.

...rflow 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 generate a random field, but I need the generated field to have a truncated marginal distributions and a correlation structure with a prescribed range. Is there an R package or functions which can do this? If there is no availabe read-to-use functions or pack...

...happening! I have a (large) object sim1, an matrix list with dim c(101,101) where each element is an 3*3 matrix. I am subsetting that with a matrix coo, of dim c(100,2), of unique indices, but the resulting object has length 99, not 100 as expected. Code reproducing the problem follows: library(RandomFields) set.seed(123) sim0 <- GaussRF(x=seq(0, 100, by=1), y=seq(0, 100, by=1), grid=TRUE, model="spherical", param=c(0, 1, 0, 10), trend=NULL, n=9, gridtriple=FALSE) simmatrices <- function(arr) # arr must be an array of rank 3...
