...ndom stream. I need to be able to select any run, say 667, and restart it exactly as it was. This project develops one approach to create replicable simulations. It blends ideas about seed management from John M. Chambers Software for Data Analysis (2008) with ideas from the snowFT package by Hana Sevcikova and Tony R. Rossini. Here's my proposal. 1. Run a preliminary program to generate an array of seeds run1: seed1.1 seed1.2 seed1.3 run2: seed2.1 seed2.2 seed2.3 run3: seed3.1 seed3.2 seed3.3 ... ... ... run1000 seed1000.1 seed1000.2 seed1000.3 This example...

...hould the dataset be raster data? Then I get: > rd<-getRasterData(x) > saveDataset(rd,"test.data") Error in .assertClass(dataset, "GDALReadOnlyDataset") : Object is not a member of class GDALReadOnlyDataset Does anybody see what am I doing wrong? Thanks. Hana Sevcikova

I'm having trouble to install RGtk2 (from source) on Mac OS 10.4.11 (R 2.9.0). The GTK libraries (2.12.11) were installed into /sw/lib via fink. Even if I set the GTK_LIBS to that path, the installation program doesn't seem to find it (see below). libglade is there too but not found. If I install the package from binaries, it fails on load. Would anybody know how to make it work?

Dear expeRts, I struggle with the following problem using snow clusters for parallel computing: I would like to specify l'Ecuyer's random number generator. Base R creates a .Random.seed of length 7, the first value indicating the kind fo random number generator. I would thus like to use the components 2 to 7 as the seed for l'Ecuyer's random number generator. By doing so, I

Hi All, I have k identical parallel pieces of code running, each using n.rand random numbers.? I would like to use the same RNG (for now), and set the seeds so that I can guarantee that there are no overlaps in the random numbers sampled by the k pieces of code.? Another side goal is to have reproducibility of my results.? In?the past I have used C with SPRNG for this task, but I'm hoping

You have not supplied a complete example, which would be good in this case because what you are suggesting could be a serious bug in R or a package. Serious journals require reproducibility these days. For example, JSS is very clear on this point. To your question >
